![[Top 150?] - Can You Do It with Frame Windows Counter @exiled_shadegd](https://i.ytimg.com/vi/Rz_LVH8OSy4/maxresdefault.jpg)

Another quick frame window vid for a somewhat recently verified impossible level. Not very interesting I know, but it's something at least. I'll paste the rest of my old description below from the full detail showcase. also sidenote this fwc is almost 2 months old LOL
"Can You Do It is an old impossible level by the infamous creator, Optic Sunflow. It was made in 1.5, when the top 1 was Definite Integral by Rabbitical, and oh man is it a monster of a level. Sometimes I wonder if Optic Sunflow was okay, because this some of this gameplay is so creatively devious, and you won't really understand till you play it. The original version was actually physically impossible in one spot, but was fixed by UltraVenom in 2019, with the ILL now using his fix as the copy.
The level's WR probably stood at 11% for years, after which HequinoX started playing this level, progressing swiftly until landing a WR of 59% in early 2023 after 4k attempts. He estimated the level to be around top 20 at the time, which actually falls in the range of our next verifier, Sulky, who started playing it around 2 weeks ago, got the WR of 64% a week later and 1.8k attempts, had a worst fail of 78% and then just verified it today in 4.4k attempts, around 3 hours ago as of publishing. It's worth noting that Sulky is a very good player, with a hardest of COMBUSTION, so of course it wasn't a mind numbingly bad experience.
Either way though, this level has some of the worst gameplay imaginable, with really awkward setups and frame perfect inputs (on 60 lol) all throughout. You'll see tomorrow with my frame window counter, but I cannot overstate how terrible some of them are for a level of this estimated difficulty (100-200). The UFO spam at 63% is very fast, nearing 15 CPS for a consistent setup, as well as a somewhat precise start to the spam, as hitting any block nearby will kill the run. Then of course we should mention the terrrible ship straightfly parts, which were probably only possible in player's dreams back then. Overall a very respectable completion, GGs to Sulky and go sub to them below!"

![[Top 10?] - CYBERPSYCHOSIS with Frame Windows Counter | Showcase](https://i.ytimg.com/vi/S81vhpJ5Hvs/mqdefault.jpg "[Top 10?] - CYBERPSYCHOSIS with Frame Windows Counter | Showcase
CYBERPSYCHOSIS is another niche upcoming top demons and maybe one of the most promising ones. It was showcased around 9 months ago by Sobean, intended to be verified by him. He ended up disliking the level to the point of dropping it, making it an open verification for a while until the top player GuilleNS took interest in the level and upgraded the visuals, with him as the new set verifier. He first posted progress of 52% with a frame perfects counter back in February, and didnt post anything else until a month ago, when he showed a best run 36-100%. His current hardest level beaten is andromeda, so hes definitely capable of this. The level is especially carried by the first 15% or so as you can probably tell. Currently all we have for an estimate is at least twice as hard as andromeda according to Guille, so itd likely place around the #10 spot right now, maybe a bit higher. Goodluck to Guille, go sub hes underrated!
This level also has special setups that force a certain alignment, so this should be one of the most accurate to actual run frame window counters.

![[Impossible?] - Haunted Corridor (ILL Ver.) with Frame Windows Counter](https://i.ytimg.com/vi/TK76DPncSzs/mqdefault.jpg "[Impossible?] - Haunted Corridor (ILL Ver.) with Frame Windows Counter
Haunted Corridor is a pretty famous impossible level by Kaotik and others that features some extreme imbalance, impossible spam and quirky gameplay (but mostly spam). The level isnt too ridiculous but some of the awkward gameplay makes the level absolutely not doable even in this state, with random chokepoints all throughout. Not to mention the spam itself at the middle and end sections is kinda crazy. Emp did an even harder version which I assume is too fast in CPS for the ILL, in 23 runs, with the spams at the cube and end waves being tighter, and more ridiculous stuff overall at the end, which would definitely dwarf this version in difficulty. I might try to find and do a frame window counter on that version, this one I was sent by a viewer who requested it (Emp themself did too actually).

![[Top 100 ILL?] - Sailent Clubvoid with Frame Windows Counter](https://i.ytimg.com/vi/Vbr7axT53OA/mqdefault.jpg "[Top 100 ILL?] - Sailent Clubvoid with Frame Windows Counter
Sailent Clubvoid is... well lets just say a level. It was made in 2.1, around 2023 and intended to be what Sailent Clubstar was to Silent Clubstep, and this thing is not afraid to hold back on difficulty, being my second hardest level Ive ever botted, surpassing Vitrification, new Rare, and maybe even kataTARTARUS and Crags of Lament. The level follows a very similar pattern to Sailent Clubstar in basically every way, which is likely why it failed the ILL QC vote a while ago (14-10).
The level of course has no shortage of impossible cube timings, with many 480s all around, especially with the classic combo string of frame perfect jumps at 44%, all 480s. The level also takes that wave in Clubstar and literally goes wild, making it like any other top ILL levels. Cant forget about the ships in this level which despite lacking frame windows often, cannot be understated in their difficulty. May I remind you this is on 480 TPS, straightfly needs to be way tighter for there to be frame windows on them.
Safe to say this thing is the hardest level I have, and probably ever will do a frame window counter on. Its just not fun man. Took over 3 hours to edit, and 4 hours to count. Fun facts tho, the level was actually buffed from the showcase on Toshs channel and became impossible on 480 TPS due to lack of playtesting. I messaged the creator and we fixed all the impossible spots. so Im fairly certain this is 100% possible now, with a little leniency incase alignment stuff occurs. Yeah this was kind of bottom of the barrel of a pick, but I thought itd be a little funny. I got some cool things planned but once again, chill on the requests and please dont take it personally if I decline.
