The title screen / UI presentation is really clean. I liked how the controls and credits are laid out. And theme-wise, yeah this is definitely a strange place lol. Rainbows, shrimp in a window, random weird stuff everywhere, it totally commits.
The art/animations are charming, and the skill tree is a cool idea (I was messing with upgrades way more than I expected). All in all, there's a lot of creative energy here, and the foundation is really cool. Nice work!
