Great story, great challenge, great art, great everything! This is a complete game, and if I did not see your development journey, I would have difficulty believing this is a jam entry.
Only issue I'd point out is more feedback on getting hit, the seagulls could come from off the screen (two times they spawned right where I rolled), and maybe an effect when on last hp left : ) I'm very glad I could play it, it's my second 30/30 + follow
