You can sense there is a ton of work here.
It's usual in jams, but the movement could get some polish.
You may already know many games apply a gravity force or a kind of pull after jumps to make them feel less "floaty" i think that would help this game a ton and it's relatively easy to implement.
In any case very good project, tho i kinda got frustrated dying all the time to those flying robots, i didn't even know they can follow you (i tried ignoring one to "speedrun" the game lol).
