Geometrical Insanity 100% (Awesome Hard Demon) by TheDevon | Geometry Dash
This level is amazing. Especially for a Geometrical Dominator remake.
Practically every part is consistent once you learn it, even the memory part (it's not like the entire level is memory, but you know which part I'm talking about), and it's super satisfying to play
Considering how old this is (early-mid 2.0), it was probably the best 2.0 level at the time, at least in terms of gameplay.
Overall, while I do think Electroman Insanity was good despite my bad experience, this one is 10 times better.
Go play it now, it's 100% worth it.
