Really good art and sound+music. Fun game mechanic with the shell and upgrades. The hit detection/collisions with some enemies (particularly the jellyfish) feels unintuitive, like the colliders don't match where the sprite center is or something.

Thanks for the feedback! You can definitely blame me for the weird collisions, I had a bit of a field day just trying to get them to work to begin with, but also keep in mind some of the enemies take 2 hits to kill (jellyfish and barracuda), so if you were worried that you weren't dealing damage, that could be the cause.
