Made it to the last level, somehow, but had to throw in the towel there
Seconding that sometimes the movement feels a little too floaty for the precision jumps needed on these maps
I think it might help if you made it so that any input overrides previous ones - for example, right now if you jump, hold left, then hold right while still in the air, you stop in place. But there are a handful of jumps that require you to make a quick switch back in the air. If you could work it out so any new input will override the last, you could make that jump much easier (but also lean into it with more hazards around them, I dunno I haven't studied kaizo level design). But I think it would also help with being able to quickly reverse your momentum for those precise jumps (at least that's how it works in my head, but it might not end up working that way in the back end when implemented)
But otherwise I really love the pixel art across the board, and the music, everything else about the submission feels really good. Great work, and thank you for helping me confirm that I am indeed not a kaizo gamer, went through like 3 biblical crashouts to make it as far as I did.
