Nostalgic for anyone that has seen Kuro Oni at least once.
Other than all of my other bosses, I ripped the models, textures, and sounds, the animations were not able to be ripped unfortunately simply because its Unity.
Boss' origin: Kuro Oni
It could have been better if I never gave up on compiling SF2 1.5.0 that is avalible, its way too hard, someone get me more Nextbots...

![[VERIFIED] Abandoned Corridor (Top 60 Solo Extreme Demon) | by Mentrillum
After 2 years, the one Death Corridor inspired level everyone might have been waiting for is finally verified after only 18k attempts. Which is a fair amount for my new hardest. This could realistically place anywhere in the demon list as I am awful at judging difficulty. It could be top 50, top 60, top 70, I dont know. All I know, I made this as hard as possible for me while still being manageable for me to get out quickly. I did 2 nerfs in the meantime, being the final spam part as it was quite luck based and one spike at the first red wave part as it gets too tricky. And of course a few small buffs just to make a part not feel free.

![[VERIFIED] Gunslinga Corridor Z (Extreme Demon) by me and more | Geometry Dash
First thing, I despise verifying this to the point I ended up nerfing the level just so I dont lose my sanity. Yes I know the difficulty was meant to drive this, but even this version is still pretty difficult. Second thing, I will never touch anything related to Gunslinga Corridor ever again, I really do not like the level. This is by far my least favorite extreme demon Ive beaten.
If you want to play this level for whatever reason, the ID is 77988199, but be warned for the torturous gameplay. [VERIFIED] Gunslinga Corridor Z (Extreme Demon) by me and more | Geometry Dash](https://i.ytimg.com/vi/i2BtDY1XX2Q/mqdefault.jpg)

![[ILL RECORD] Unnerfed The Hell Zone 26% + 40%-92%
Havent quite left GD yet, I got bored and decided to pick a random ILL level to go for and the most logical one was The Hell Zone that Cyclic released. This level is unique in which 240hz completions are not possible as there are multiple frame perfects stacked on top of each other making a 0% run basically impossible, still physically possible but not humanly impossible. To solve this you need to lower the refresh rate, 60hz seemed like a solution but 144hz is the best way to go in my opinion as you have the least input delays and have smooth gameplay, it makes both 2% and 24% doable. So you can expect me to beat this soon, not sure if before 2.2 though. [ILL RECORD] Unnerfed The Hell Zone 26% + 40%-92%](https://i.ytimg.com/vi/iU9AKu3VnS4/mqdefault.jpg)
