atari2600land is continously improving his Jellyfishing game featuring SpongeBob SquarePants.

Release notes for yesterdays second version:

Here’s a little sound effect. The more jellyfish that are near you, the louder the buzzing is. Does anyone have a good idea about how to do collision detection for stinging (death?) Since I’m using flickering, i don’t really have a good idea on how to do it.
