This is a deceptively fun puzzle game! It seems simple but it actually gets kinda hard later on! Or maybe I'm just not that good at games...
Either way, I have some things to say.
The music and graphics were solid!
The controls felt fine, but jumping felt a bit weird. If there's no coyote time, then that's probably why that's the case.
The tutorial could've been improved by showing the "change shape" key at a point where you'll actually need to use it. I didn't read it clearly at the start and had to look it up later on. Though, again, that might be just me.
The theme was implemented pretty cleverly here! Great game!
