Lets just say that playing this level reminded me of one fact I already did know but forgot about, KaotikJumper cannot make gameplay in any of his levels. This level just jumps from easy to hard over and over again, its maddening, and the only real difficult parts lie at the waves right after 20%, while everything else is mostly easy. Let me just quickly summarize some highlights of this level that deserve a mention.
The copy and pasted parts at 50% and 80% are somehow even worse than in Sakupen Hell, with Sakupen Hell you can somehow get consistent with both parts that were copy and pasted without much struggle, in this level these 2 parts are right next to more annoying parts that getting consistent at them is a pipe drain. Then you have the 20% wave which punishes you for not going really high with the mini wave and not doing a precise wave timing that is hard to draw mentally on how to do it consistently. At the core, this is a pointless Sakupen Hell spinoff level I despise. Do not play this level.

![[VERIFIED] Abandoned Corridor Update (Top 40 Solo Extreme Demon) | by Mentrillum
After being neglected to be rated because it is a disjointed mess, I have returned back to Abandoned Corridor and give it a upgrade and buff it in the process after 19k attempts. This is by far my new hardest despite the tiny nerfs I did which may make it a top 45 instead of a top 40. After clutching with a wave and ship swap, I beat this level extremely quickly.

![[ILL COMPLETION] 9o Circles by llZestll | Geometry Dash
What an experience, I first did this level with a Logitech G502 but couldnt finish it due to the input lag and the fact it was quite hard to use on wave levels. But ever since I got the SayoDevice, that helped my wave skills a lot and one level I forgot about was 9o Circles, so I decided to do it and for some reason I beat this in 40 minutes.

![[ILL But not actually ILL Record] Geometry Dash | After Sonic Wave 65%
Very unbalanced Sonic Wave, although can be a bit fun in some spots, such as after the transition in the drop wave. After 65% is basically a road block due to a very tight consistency click part, but passing that makes you beat the rest of the level assuming you dont mess up badly. Not sure if this would count as an ILL record due to me taking a different route that is equally as hard as the original route. My quest continues if you can guess what Im doing...
