I feel like the flashlight mechanic becomes pointless when every time I use it a fish attacks me, especially since you can't recover health. It could also use a bit more polish, like a more consistent artstyle and font. It is a fun concept though.

I think the game is a little bit slow, you can increase the speed for the sub, also I think is will be better if we have a restart button because sometimes I try all the possible ways and it leads to the wrong way, so I just want to restart and try another one. and the fish(shark) sometimes will be flipped over for some reasons!
