I like the screens that show the different parts of the game world. The music is nice too.
The fishing mechanic was cool, but I didn't know I could move for a while. Some on screen text telling me the controls when I needed to know would have been awesome (I wasn't able to include tutorial elements in my game). I felt a bit frustrated with the player's move speed in the water. The fact that you get an aimable harpoon gun is awesome and the addition of a flashlight immerses me even more and adds another layer to the game.
Well done, I enjoyed playing your game.
