Cool idea, but maybe giving the player the ability to go up and down while falling could improve it.

Simply yet fun. Idea of combining your field of view and the health bar is very creative. Also, if you have time, please take a look at my game, thanks.

MASTER PIECE!!!!!!!!!!!!!!!!!! and I'm not just saying that because I was on the dev team 

This game is really cool!

It's fun to play, the music is catchy and the graphics are simple but effective.

The theme is very well respected and it's more original than a simple scuba dive.

The game is almost perfect for a game jam except for one detail:

It's slightly too hard (I think the enemies go too fast). It would have required increasing difficulty with depth. (the deeper you are, the more enemies there are and the faster they are)
