Scream Machine by TMco 100% (Top 90 Extreme Demon) | New Hardest and 1st French Victor :D sleyyz 2024-10-16 | New hardest! yaaaaayyy!!!!! Clap clap clap.attempts: 6098difficulty: top 82 (low tier 33 on GDDL)my opinion: slightly harder than cognition sounds good to me (at least top 87, low tier 33) also defo easier than fragile imolevel rating: 90/100, despite the inconsistency, the gameplay is p fun and the deco/atmosphere is peak enjoyment: 55/100fails: 62%x12, 65%x3, 66%x2, 67%x2, 68%, 70%x3, 71%x3, 72%, 73%, 74%x2, 75%x2, 76%, 80%, 98%x2144hz 360fps bypass, no cbfI absolutely do not recommend it as a hardestMy top 5 right naw:1- Scream machine2- Gracefully3- Kowareta4- Plasma pulse finale5- Random Access MemoryWhat a painful experience it was for the small amount of time this took me. I started playing it around 2 weeks ago and got some really good runs pretty quickly, having literally 5-100% done in about 5 days, and then doing my first 98% fail just a day later, which was a fluke from 62% btw (less than 4k attempts too). I had so much fun in that first week, unfortunately the level has a lot of issues mainly in the second half of it IMO, which kicked my ass in my second week of playing.,;..,, There are a lot of stupid chokepoints and actual RNG in the level that makes it extremely inconsistent, the most noticeable one being that horrendous 62% pink orb. Overall, 62-75% is just stupidly inconsistent. And the most frustrating thing is that the first 40%, except like 1 or 2 hard clicks, are EXTREMELY consistent, which basically makes every attempt last at least a minute to die of something real stupid and get mad af about it (and also the reason why i dont have that many attempts). It's without a doubt one of the most mentally challenging list level compared to how hard the gameplay actually is. It took me a whole week to get back to 98% again because of all that (which i died to again), and then proceeded to beat it 2 days later. i forgot to mention that the last click is ass rng bullshit too of courseFavorite parts: 18-38%, those are really weird parts when you first learn them, but it gets so consistent and fun once you get it, plus it's some of the only parts where there is no actual huge chokepoint (idek how the 20% timings get consistent but it does) 50-61%, amazing intensity and really fun too, very satisfying to pull offLeast favorite parts: 62-75%, of course inconsistent ass garbage go vroooooom, 62% click is the worst of the level, 67% ufo is really weird, 70% ship transition is quite annoying, I also really don't like 71-73%, plus the 74% ship which is partially blind, making it real unfair cuz of how difficult it is. 98-100%, gambling dumenHardest parts: 5-13%, in my opinion the hardest part, but because it gets consistent quickly AND its at the beginning of the level, it's really not that bad and actually even p fun, probably my 3rd or 4th favorite part of the level tbh 38-50%, this one I don't really like as much, there are some very weird clicks (slope gameplay woohoo), and some of the timings vary a lot depending on how you did the clicks before, making it pretty damn hard, would say it's the second hardest part.I would not consider any part of the second half to be one of the hardest, because it's really more inconsistent than actually difficult lolAlso that 1/100 certain death at 24% easter egg was really unnecessary, thank you.
Kowareta by Gablor 100% (gambling demon) ((second hardest!!!))) sleyyz 2024-08-29 | this level unalived my gambling addiction, bad but satisfying to pull off, still fricking bad, dont fridging play thisattempts: 18500 (round number W)gddl tier: 32in my onion: tier 32enjoyment 3/10worst fails: 81%, 84%, 85%, 86%x2drop attempts: i didnt count but if i had to guess i would say around 30-35 drop attempts240fps, no cbf new second hardest, it was right next to plasma pulse finale on the demonlist and i honestly have no clue how its even possible, it was so much harder for me (im a xl carried fraud that cannot play short levels so dont trust)top 5 update1. Gracefully2. Kowareta3. Plasma pulse finale4. Random access memory5. Super probably leveli might have forgotten a level or two cuz im dumb cuz im stupid also i think thats like my best thumbnail ever im so goodggs
Boss Rush by GDTiclos World Record Again (2:59.587) sleyyz 2024-07-16 | here we go again, first sub 3:00, quite mad that ive choked sirius that badly though, it could have been way better, but hey i still did itthanks to @yomayoCB for finding some strats (most optimal Anemone route and room between BEE - Sirius), the run would have probably been impossible without those strats or extremely hard, and go support him because he has put a lot of effort into speedrunning it and will most likely get the world record pretty soon! go check out @Pillownsalt too tbhim not gonna continue speedrunning this, trying to get the perfect run is too infuriating for me lmao, good luck to everyone else
Gracefully by NindyBK and More 100% (extreme demon) | New Hardest ! sleyyz 2024-03-31 | sorry for the bad quality, the level's optimization is so bad (obs and my pc too) that i have to record like this lmaohonestly, the level's balancing is not good and some parts are very inconsistent, but i still found it very fun to play somehow, imo the gameplay is quite goodsong and deco are also banger if you dont count the optimization :fire:enjoyment: 8/10attempts: too many, idfk due to my game crashing every fricking time but i would guess something like 9k recent + 5k old (i have no clue dont trust)difficulty: #110 on the demonlist as of date of completion, high tier 32 on gddlpersonal opinion: from the levels ive played in the demonlist, its definitely a lot harder than ppf, and weirdly enough i find it harder than ragnarok, which imo is very overrated right now or its just my skillset being shit, idk, definitely high tier 32 thoworst deaths: 69%, 70%x2, 71%x2, 76%, 80%, 88%good game
boss rush by gdticlos world record (3:01.51) sleyyz 2024-03-20 | I only uploaded that for people to stop asking me how i did it btwI wanted to get sub 3:00 but my sanity was going down at the speed of lightit is possible as I failed the rooms in between the bosses, was kinda slow on anemone + lost a second on the second phase of sirius but yeah its very hard, definitely extreme demon difficulty
The Abyss 100% (top 1 platformer) sleyyz 2024-01-21 | 6 hours of playtime (had 3 hours of practice beforehand)3722 attemptsnew platformer hardest ggsenjoyment: 3/10difficulty; top 1 dumen very hardonly have the g4lvatron extreme to complete to actually have all platformers leveles done
PLASMA PULSE FINALE by xSmokes and Giron 100% (Extreme Demon) | new hardest !! sleyyz 2024-01-15 | fun but painful at the same timeenjoyment: 7/10attempts: 4 497 (+ ~7k old attempts)difficulty: #136 as of date of completion, low tier 32 on gddlpersonal opinion: idk i not good but it is somewhat hard i guess!worst death: 98% (bangerrr)it didnt really feel like a new hardest for some reasons, maybe because i got a huge skill boost after random access memory since i started playing on up arrow, who knows
SUPER PROBABLY LEVEL by Alkali 100% (exytrtme demon) my 2nd hardest!! sleyyz 2023-11-27 | do not play this level no matter what, my least favorite level of the gamedifficulty: impossiblegddl tier: 29my opinion: high tier 29 or maybe even low 30 enjoyment: 0/10attempts: between 10k and 11k idk exactly due to data loss2nd hardest
Ragnarok 74% (next hardest probably) (filler) sleyyz 2023-07-10 | fillerthx ox1y1gen for the beautiful thumbnail----------------------------------8884 attemptsother cool runs: 63-100% x4, 57-100%, 16-79%, 64%, 60% x2enlex is impossibleright now i would say its overrated, imo it was correctly placed before (below bloodlust)
Molten Mercury by ItsHybrid 100% (Extreme Demon) | 1000TH DEMON :D sleyyz 2023-05-27 | It was not very fun to play, just midAll of the difficulty comes from the waves, as a non wave carried person i did not enjoy this, dying 80% of the time from the waves.I was reaching the second half of the level in literally half of my attempts near the end, but got quite unlucky with like 40+ second half deaths and 2 ending deaths.I'm still very happy to finally reach 1000 demons cleared ig !!!!!144Hz, bypassed to 240fpsAttempts: 3092Difficulty: Harder than bloodbath, easier than blade of justice (tier 25 on gddl)Enjoyment: 5/10worst deaths: 92%, 93%5th hardest if I'm not wrong i do not remember#moltenmidcury
RANDOM ACCESS MEMORY by Acute144 & More 100% (new hardest :DDDD) sleyyz 2023-05-03 | This took me so long to beat but ive finally done it !I got quite unlucky, dying probably around 20 times after 75%, but i still enjoyed it a lot !144Hz, bypassed to 240Fpsattempts: 11441difficulty: #109 on the demonlist (03/05/2023), tier 31 on the gddlmy difficulty opinion: dont have enough experience in this difficulty range but sounds about right, harder than sonic wave imoenjoyment: 9/10 even though i got quite unluckydeaths: 92% x5I honestly think this is one of the best memory extreme, and one of the best level on the demon list (my 2nd favorite memory level bellow Triple Six)Btw this was absolutely not for Maymory but hey, good timing I guess :tro:I first thought that the dual and the wave (25-50%) were the least consistent and hardest parts, but after thousands of attempts i somehow was more consistent at those parts than the last quarter of the level.I think the hardest part is still the wave (35-50%), the dual gets quite easy and consistent when you understand what you're doing (took me a while to figure it out) The rest of the level (0-20%, 50-70%) is fairly easy, it takes quite some time to learn the 50% cube maze but its like the most consistent thing ever made I'm so happy to finally beat a new hardest, originally found and tried this level because i'm a big fan of this song, also getting closer to my main goal, beating a main list :DD(sorry for bad recording quality i dont want to have a lag spike every 2 seconds, it would make the level unplayable lol)hi
