Nothing to say about this level aside from the first 1800 rooms being insanely boring and easy with some exceptions. with how short even the difficult checkpoints are I don't feel this should be rated extreme demon as long levels are often just glazed by the community for being an 'endurance test' while in reality this took way less time to beat than nearly every other single extreme demon platformer I've played WITH practice, this level didn't even need practice and only took about two hours. and that time would've been nearer to about 40 minutes id say had the free rooms not been a thing.
another thing is I feel this level is horrendously plain and simple, and that its only rated for difficulty alone, it has very little designs aside from minute changes in the backgrounds between levels at times, at only the occasional change of colour between floors.
Level isn't bad exactly, but it's not great either, it's very boring for the first 90 minutes as a lot of the rooms are mindless and pose no challenge to beat.
