Nice and cozy, liked the controls. Can agree with some other comments about a goal, and after a while it also seemed like I couldn't loose HP any more (got down to 70 and then it didn't go down no matter how I hit the surroundings). Good job!
You basically level up after gettin 10 fishes then can resist the second level of pressure, we were planning to add more levels but time ran out. You can restore health by going to the surface but it's not really necessary in this version.
