Fun and super hard! Finished level 1 and got a bit into the jello level. Gives me Animal Well vibes.
The "hidden" mechanics are great: holding jump for longer bubble bounce, holding sprint for bubble spit distance. Expands what you can do with a simple mechanic.
I would have loved a persistent save mechanic. I wanted to come back to it later but couldn't cloes the tab without losing progress. But maybe that's part of an intentional arcade-style choice. And I fumbled some inputs with the keyboard layout. Probably a skill issue though.
Cute characters, clean pixel art, and the checkpoint system is appreciated.
