Lovely game. I really like that the main mechanic is quite simple, but very elegant and exciting to use! Everything was mostly tutorialized well, but I think that (at least the first world) gets quite hard very quickly. And modestly I'm decent at 2d platformers (finished celeste's c-sides and hollow knight's path of pain), but some screens felt a bit too long for being so early in the game.
Some stuff felt kinda mean, like the pillar of spikes where you have to superjump to get out - I get that you're making a precision platformer but it felt a bit too precise, for being so early at least (still they were some cool jumps).
But still the music, sfx and the character design for the little eye (?) guy are nice. Best of luck for future game devving!
