I like the uplifting graphics and tune you have in this game! It can be a little tricky to tell if you're making much progress in the game by just going downwards, I can't help but feel I may be missing possible treasure on the left and right sides of the game level but my sub moves a little too slow for me to want to check. I guess that could be intentional.

Overall, nice looking and sounding first game jam game, congrats on getting in done in 48 hours!
