This is a small game, but I like it a lot actually. The idea of being a fish trying to return to the water but all you can do is struggle and flop is very interesting to me.

I've noticed this with a few of the games from the jam but it seems like you just found a single asset from those we were given and created your game based on that instead of forcing yourself to combine and figure out how to use some of the strange things we were given. I think it would be interesting if you implemented several levels which grew stranger and stranger as the incorporate more of the strange assets we were given. 

Additionally, I think this would be a great idea for a physics game so instead of using what seems to be some applied force to jump and "I don't know how" to wiggle it might be more interesting if you were to use the inputs to like contort the fish's body to bend in one direction or another and you have to use that motion to get you back to the water.
