Neat! Love the neon aesthetic overall. The volume did blast my ears out on first launch though.
I think some of the difficulty will feel better if you put a few small jumps just before big jumps, kind of like warming up or getting a running start. There is a particular checkpoint that has a 3-3-2 jump within a second of spawning that I got stuck on for a bit because I couldn't prepare myself for the timing fast enough.
Otherwise nicely done!
