This isn't very professional but you just move around the sea w/ the arrow keys.
In the remix, you can now jump out of the water*, and the school of fish and the crab move. The treasure chest also opens and closes and on one screen there is a jellyfish that moves. The original project is by @redgreenandblue. *If the jump doesn't work and you stop in the air, then just press the down key until you are in the water again.
