I set my name as "fart" because mentally I'm 2 years old
I already knew from the screenshots and menu that I was in for a polished experience.
The music, sounds and graphics on display are so good! And the gameplay itself was incredibly simple, but so fun as well. I love murdering fish. (that sounds bad)
I guess my only criticism is the fact that the How To Play text is really long to scroll through. I'd have preferred a bit of text showing up at the start that says something like "Use WASD to move, press Space to dive, collect pearls" and then fades away, or a fully interactive tutorial, though that latter idea probably wouldn't have worked in a 7 day jam.
Incredibly solid time!
