Great game idea, even my first plan was to make a game like this but in 3D, Yours is very cool too, i enjoyed playing it. I reached the end but the game didnt show any end scene or ended itself. The background audio is also very good and adds to the underwater atmosphere the controls are good too. if the light on the player's head would move in direction of mouse it would be great little improvment. Superb game overall. :D
