SKWAD Cypher Verified! [1.9 Top 5] Slithium 2023-05-25 | DISCLAIMER TOP 5 ON 1.9 NOT 2.1Huge thanks to Cersia for giving me the opportunity to verify this, overall had a lot of fun even though I was getting frustrated towards the end. Tried my best to make this as fun as possible while still being a challenge. Probably low extended list difficulty on 2.1 but take that with a grain of saltAttempts: 1774 verifying, 3641 from playtestingIn-game rating: N/AMy difficulty rating: Extreme DemonEnjoyment: 8/10Hardest part: MagmetaList placement: N/AMy placement: Mid-low extended1.9 placement: N/AMy 1.9 placement: #5-9
Molten Core 100% Slithium 2023-05-12 | Started off annoying but I had a lot of fun with the rebeat surprisingly (wasn't recording the first time), decent level ig but has some annoying spots that really should've been fixed with how many verifiers and updates this level has had.Attempts: 634 (+32 for the rebeat)In-game rating: Extreme DemonMy difficulty rating: Extreme DemonEnjoyment: 8.5/10Hardest part: 66-84%List placement: #103 (?how?)My placement: #305-318 (between Bloodbath and Phobos)
Slaughterhouse 49-100% Slithium 2023-05-05 | Having a lot of fun with this, most parts got surprisingly consistent for how hard they are. Unfortunately 43 and 60 suck and I can't imagine this level being fun from 0
Slaughterhouse 25-63% Slithium 2023-05-04 | this wave is OP i dont even know what it is but im good wit itidk how i passed the 60% click first try after passing river, might go for this sometime but damn is it hard
Sonic Wave Infinity 48% (Top 1 Riot/Viprin ver, former WR) Slithium 2023-03-24 | This is the version Riot gave me to verify in 2021. This sits 34 spots above Acheron on the impossible levels list and would likely place top 1 today. Started playing this for fun the other day and was surprised at how consistent I was, I got this run on my second drop attempt somehow.Previous record was 45% by Photonic
COMBUSTION 82% (VERIFYING) Slithium 2023-03-10 | NEAR THE END NOW BOYShopefully the ending doesn't kick my ass too hard, the last 20% of this level is brutal
COMBUSTION 52-100% (Verifying) Slithium 2023-03-05 | Have the level in 2 runs now. Everything after 40% in this level is so damn hard for me, slow timing gameplay is the polar opposite of my skillset and I can't get consistent at the second half no matter how many thousands of attempts I pour into itSorry about no clicks, didn't realize my mic was unplugged but I really don't want to do this run again right now
COMBUSTION (Top 30) [Preview] Slithium 2023-02-28 | A couple years back Cersia and I got the idea to build a slow timing level using pain engine (originally on 1.9) but despite the layout being finished it never came to fruition. Around a week ago I asked Cersia if he wants to build another layout with the same song on 2.1 and he was able to decorate it extremely fast! I absolutely love how the level turned out and I'm looking forward to verifying it soon.(This footage is botted and is not legitimate)
The Catacombs 44% (1.9 GDPS Top 1) (Verifying) Slithium 2023-02-09 | Filler upload but I'm hoping to verify this in the next few days. I personally don't find this harder than Sky Shredder but everyone else thinks this is top 1 so they're probably right lol~8k attempts so far including old
SKWAD Layout (Upcoming Top 20 Extreme Demon) Slithium 2023-02-04 | we at the SKWAD made a level together and it is awesomethis is getting decorated :DGameplay parts (in order):0:00 - Enderlink6750:08 - kyder0:17 - VoltreN0:25 - Magmeta0:33 - Cersia0:41 - hynter0:49 - Slithium0:57 - tenzhii/zo1:04 - Melody1:12 - Cersia (again)Level hosted by CersiaFound motivation to play this game again, been making some small progress on Slaughterhouse and trying to finish my projects again. Sorry I was gone so long lmao college got in the way of me having time to do anything
Virulent Venture 55-100% (verifying) Slithium 2022-05-11 | Level is basically finished! The wave deco makes it so much harder its insaneNew deco by Motheye: youtube.com/channel/UCC4GYXPD1OHwafWVeLDlRSQ
Minions by Tacomacho 100% (the demon) Slithium 2022-01-14 | minions i love themAttempts: 19In-game rating: minionMy difficulty rating: the minionEnjoyment: minions i love themHardest part: banansList placement: super probably levelMy placement: #2
Virulent Venture (Preview #2) Slithium 2021-12-09 | New parts by tmoney and Shaun_07!The level has 2 more parts to be finished, so expect a final preview soon! Deco is probably final but I'll improve the transitions between parts to make the deco flow better throughout the level.
Devil Vortex 100% Slithium 2021-10-03 | Sorry for the inactivity + bad mic, I left my snowball at my dad's house so I was stuck with my webcam mic lolI always hated this level in the past and assumed it would be horrible to play but this is some of the most fun I've had playing this game in a long time, this level is SUPER consistent from 0 to the point where I was getting to the wave spam almost every attempt and getting to 60 every couple of minutesAs for difficulty its also extremely overrated, on no planet is this anywhere near Artificial Ascent difficulty in my opinion, nevermind 24 spots higherAttempts: 991In-game rating: Extreme DemonMy difficulty rating: Extreme DemonEnjoyment: 10/10Hardest part: Every wave past 50%List placement: #71My placement: #95Also I didn't drop Cimmerian Shade I'm just taking a break + focusing on university
Cimmerian Shade 45% Slithium 2021-08-24 | OBS messed up the game audio sync so I edited the song over it but here's the unedited w clicks: youtu.be/5okhOquuxv8I know it's only a 7% difference from my 38% run but I wanted to post this since its both past the hardest part of the level and it now means I have connecting runs! I have no idea how I'm progressing so fast (btw the level is getting a deco revamp soon)12374 attempts so far
Cimmerian Shade 45-100% Slithium 2021-08-22 | I got unlucky with this run with 2 deaths at 96% lol, glad to have done it thoughI guess I'm going for this level now, although I've played the dual wave for a bit and have only been able to do it once so we'll see
Unnamed Extreme Demon Layout #2 Slithium 2021-08-09 | The sequelI'm not sure if I like this more than the other one I posted 6 months ago but it's still pretty fun, although it's really second half heavy right now I'll definitely try to balance it better when I verify itbtw this is being decorated by TomsoN
Fissure Verified (Insane Demon) Slithium 2021-08-04 | Very fun insane demon I got the chance to verify!ID: 72193089Attempts: 128In-game rating: N/AMy difficulty rating: 7/10 (Insane Demon)Enjoyment: 8/10Hardest part: 34-42%Worst fail: 96%List placement: N/AMy placement: N/ASong: "Fracture" by Rukkus; youtube.com/watch?v=CWPdmj1t-CE
Virulent Venture (Preview #1) Slithium 2021-07-21 | Parts by Sargist and Kyder!If you remember that layout I posted a while back, this is the same level. Progress is going well, expect to see this done soon!(Sorry for not uploading in a long time, uploads back on schedule soon as I'm getting my motivation for this game back)
Ricochet Full Layout [Top 10?] Slithium 2021-06-02 | Sorry for not uploading in a while, I've been super busy with school but I'm finally finished! I know I said I'd go for SWI when that's out but the level is physically impossible for me because of a microclick in the first wave so there's a dream goneAnyways this layout was built by me and a few friends, I'm still looking to find decorators so if you're good dm me on discord Slithium#30000:00 — Dagger0:12 — Slithium0:15 — Cheesy/Lasaga0:24 — Zephlix0:30 — hynter0:36 — Slithium0:47 — Slithium/sargist0:59 — Cersia/Cersia1:11 — Slithium/IsaneSong - Ricochet Love by Waterflame
Sonic Wave Rebirth 100% Slithium 2021-04-28 | Extended ball challengeSorry for not uploading in a long time, I was verifying Aerial Gleam but dropped it because end wanted me to nerf it and I didn't want to beat a nerfed version after playing my buffed one for a week. Also I'm verifying SWI now so expect a stream soon!Edit: since I didn't seem to explain this well enough, I was taking too long on the level and end just wanted it out so he told me to nerf it. But beating the easier version wouldn't have been satisfying at all and would've made the experience even more miserable because then it would just feel like a chore and I wouldn't be having fun with it, and I was already stressed enough with schoolAlso music is edited in because I'm having issues with OBS delaying desktop audio for some reason that I cannot figure outAttempts: 157In-game rating: Extreme DemonMy difficulty rating: 9/10 (Extreme Demon)Enjoyment: 7.5/10Hardest part: take a guess yes you are right its the ballWorst fail: 65%List placement: N/AMy placement: #74Song: newgrounds.com/audio/listen/684658
Vindicate by Cersia 100% (Unrated Extreme) Slithium 2021-03-25 | I beat this back in October last year but forgot to publish the video until now oopsWhile I didn't really enjoy this level everyone seems to like it, the deco is also very good for being made in the 1.9 editorID: 65234442Enjoyment: 3/10
Hyper Paracosm 100% Slithium 2021-03-17 | This level was actually pretty fun, I was getting super unlucky and kept dying right at the end of the wave but I only had 1 death at the postdrop which was the first click, but the wave itself is super consistent and I was basically getting far every attempt. I'm not sure what my attempt count is since I have old attempts from as old as 2019 but it took 776 after coming back to it today.Attempts: UnsureIn-game rating: Extreme DemonMy difficulty rating: 10/10 (Extreme Demon)Enjoyment: 8/10Hardest part: 64-100%Worst fail: 64%List placement: #27My placement: #33Level song: NK - TruthOrDareMenu song: Monkey's Delivery Service - MOTHER 3
Aquatic Auroras 100% (Extreme Demon) Slithium 2021-03-16 | Ok that was weird, I spent about 2k on the old version of this but stopped playing because I couldn't run the update, but the list team released an LDM a few days ago and I beat it in about 20 minutes of playing with a fluke from 34% on this version (and 64% on the old version). I can't say I really recommend it though as the balancing isn't very good and it probably would've been miserable if I didn't get lucky.Attempts: ~2.4kIn-game rating: Extreme DemonMy difficulty rating: 10/10 (Extreme Demon)Enjoyment: 5/10Hardest part: First wave probablyWorst fail: 34% (64% on old version)List placement: #21My placement: #33Level song: NK - HeadrushMenu song: Monkey's Delivery Service - MOTHER 3
Scary Decode II coming soon Slithium 2021-03-12 | I didn't have time to verify this today but I wanted to at least show some of it, and no better part is there to show than the last wave
Friday Vortex 100% - Extreme NC layout by Cersia (Unnerfed + buffed) Slithium 2021-03-04 | I thought I was having awful luck because I kept dying to easy spots past 45, but I somehow fluked it from 67?? I think this is my 3rd hardest but I could be overrating it because I beat it in a day, although I had a bit of practice from a few months ago when the layout was first made.Anyways this was a ton of fun to beat, and will hopefully get decorated in the future
Unnamed Extreme Demon Layout #1 Slithium 2021-02-05 | (Noclip was used for this recording)Sorry for the stuttering, blame OBSI finished something in 2.1 for the first time in a while, and its definitely my most fun layout. I tried to build it so that it requires a balanced skillset, with hard wave, timing, and ship parts.Will be decorated after Ricochet is finished, though if anyone wants to decorate it before that pm me on discord Slithium#3000Here's the ID if you want to play it: 66888484
Glacial Reflections by Artsi 100% Slithium 2020-12-30 | Note: I cut out the pause screen at 0:09, if you want me to upload the uncut footage I can (Also sorry for quiet mic)Cool unrated NC by Artsi, I had fun with it but some of the transitions are annoying. I recommend it if you want to go for an NC harder than levels like Crimson Clutter and TSB, but easier than HR and Down Bass.Attempts: 241In-game rating: Insane unratedMy difficulty rating: 7/10 (Insane Demon)Enjoyment: 6/10Hardest part: 19-31% probablyWorst fail: 88%Unrated Demons List placement: #27My placement: Not list worthy
Aerial Gleam Layout 44-100% Slithium 2020-12-17 | Not verifying, just found a copy of the layout on the servers and buffed it for fun. I had to nerf a couple parts because they were super inconsistent and I was dying there almost every time but overall this run was pretty fun to do. I'd say this version is harder than both Aquatic Auroras and Arctic Lights by quite a lot
Calamity 54% (No longer verifying) Slithium 2020-11-30 | I got this over a month ago but didn't upload it, this version is a bit outdated but it includes most of the buffs I did to the first wave.Also I was in a call I just had my desktop audio muted which is why I'm yelling at the end and why there's no music at the beginningKurumi is the new verifier
Plasma Pulse Finale 100% (Extreme Demon) Slithium 2020-11-29 | Awesome level, only bad thing is its super unbalanced but if you can get past that its good (also 89 sucks but I somehow fluked it)Texture pack by ryamu: youtube.com/watch?v=Yy40vMMVYMsMashup by paqoeSong by BoomkittyAttempts: 4637In-game rating: Extreme DemonMy difficulty rating: 10/10 (Extreme Demon)Enjoyment: 10/10Hardest part: 87-89%Worst fail: 88%List placement: #23My placement: #23
Plasma Pulse Finale 74% Slithium 2020-11-11 | I fluked a bunch of hard spots and then died at the easiest part of the level what is wrong with meRemix by paqoe i think i cant remember
I beat Zaphkiel in 1 attempt in the middle of class Slithium 2020-10-06 | I have no idea how I even did this. Probably the craziest thing that's happened to me in this game. Decided to start playing and literally beat it first attempt. This level is pretty weird, started off unenjoyable but got more fun the more I played it. Everything before the third wave gets insanely consistent to the point where I was getting to the lava part every couple minutes and dying to a bad transition somewhere in the 2nd half. Overall not too bad, just a bit frustrating when every attempt you're dying to the same spots in the 2nd half over and over again.Attempts: 2530In-game rating: Extreme DemonMy difficulty rating: 9/10 (Extreme Demon)Enjoyment: 7/10Hardest parts: Third wave and final dualsWorst fail: 80%List placement: 45My placement: 55 (Weird experience so I'm not entirely sure but it's definitely easier than Catalyze)I'll probably have to rebeat this for the list because I muted desktop OBS audio as well as my in-game music because of class so I don't have pulses oops
Wonderpunch Layout by Gabs 100% (Fluke from 10%) Slithium 2020-10-06 | Really fun NC layout by Gabs, would be cool to see this decorated
Balengu Vortex 100% (Extreme Demon) Slithium 2020-09-28 | Very cool NC level by Temp, I'm not too sure if I enjoyed it though since its super unbalanced and most of the difficulty comes from the first 40% of the level and then drops off significantly in difficulty after that. I also got very unlucky with multiple deaths past 60% but overall its not too bad to play if you're patient. As for difficulty, I'm not sure if it's harder than Bausha since it's been a while since I've played it.Sorry that I keep delaying Vengeance, if I'm being honest I'm just not having fun with the level anymore.Attempts: 1604In-game rating: Extreme DemonMy difficulty rating: 9/10 (Extreme Demon)Enjoyment: 5/10Hardest parts: Memory cube + first waveWorst fail: 80%List placement: #78My placement: don't know
Carcano 100% (Extreme Demon) Slithium 2020-09-26 | Sorry about quiet mic, my game audio wasn't turned down enough in OBSWhen this level was originally released the movements in the first wave were very odd and it was extremely annoying dying to it over and over again every attempt, and even dying past it was annoying because it felt like a waste of an attempt and that it would be a while until I got past it againAsuith recently updated the level nerfing the first wave and 61% which made the level much more enjoyable, I highly recommend playing this nowAs for difficulty I think this is harder than Auditory Breaker and Artificial Ascent, but easier than Catalyze.Attempts: 3342In-game rating: Extreme DemonMy difficulty rating: 9/10 (Extreme Demon)Enjoyment: 10/10Hardest parts: Last cube + 40-60% sectionWorst fail: 87%List placement: N/AMy placement: 55-62

Annihilation Nation 100% (Extreme Demon) Slithium 2020-09-20 | I swear I have the weirdest skillset in the game because this took me 35 minutes to learn and beat; honestly I found both Triple Six and The End to be much harder than this. Anyway very good level I recommendAttempts: 249 + a practice run I accidentally deleted while trying to make a copy oops im smartIn-game rating: Extreme DemonMy difficulty rating: 6/10 (Hard Demon)Enjoyment: 10/10Hardest part: 2nd waveWorst fail: 67%List placement: #146My placement: Legacy (around Cataclysm/Falling Up)
The End by Zylenox 100% Slithium 2020-09-10 | Awesome level, although the gameplay is a bit weird and buggy at parts(Had to beat on LDM because of lag, full detail looks a lot better)Attempts: 463In-game rating: Unrated InsaneMy difficulty rating: 7/10 (Insane Demon)Enjoyment: 7/10Hardest part: 85-95%Worst fail: 94%List placement: N/AMy placement: N/A

Sweeping Demon II 56 - 69% Slithium 2020-08-29 | I know this doesn't look *that* hard but I promise you its the hardest wave I've ever played including SWI's last wave (I don't play challenges), there is ZERO consistency and you can't see a lot of the spikes. The robot at the beginning too is really hard because for the 2nd click you have to hold slightly longer than the other clicks but not too long or it kills you. This level is fucking insane
