The hitbox of the fish is bigger than its sprite, right? I guess it gives me an excuse for not being able to beat the boss.
The game is cool, it looks and sounds pretty good, it's satisfying to control, I like the patterns, the very low hp enemies and the bouncing mechanic is a fun use of the theme to deal with, I like it. I like that the game feels underwater while not being slow, and the difficulty is fine for me.
Thanks for sharing.
