Hello!
Congrats on this work! I really appreciated the immersion I felt while playing. It was super relaxing, and the music played a big role in that, it really made me feel like I was deep in the ocean. The graphics are also really cool!
At first, I thought it would be a game like Angry Shark, but it turned out to be something completely different! The gameplay is easy to pick up and very intuitive.
As for an improvement, maybe adding a fullscreen option could be nice (unless I missed the key for it or you simply didn’t have time to include it). Also, it fit the jam theme for me !
