Really nice Maze-like game! I included it in my Dive Jam compilation video, if you’d like to take a look :)

I accidentally looked at the whole map in your screenshots before I played, so I kinda cheated. I thought the player's treading water animation was great! Would've loved to see a couple more animations. And the end splash screen was great too like Diver said.

I loved that final scene at the end of the game! I think this game would be perfect for you to make more pixel art assets as you have a working game loop! About the game mechanic, I found it a bit hard and needed the map at the end because, first, I suck, but also because if you took the wrong path once, you were pretty much done. So instead of being a game of luck until you remember the path completely, I would offer a littlemore  air time, or time it in a way that it allows you barely to make it back to the previous source of air if you spotted early enough that you were on the wrong path. Thank you for surviving DiveJam! You made it, you made a game!
