atari2600land is working on another new game. Aquarium is going to be a Tamagotchi style game, but you’ve to take care of your fish.

Release notes:

Added FEED option. Another idea for an option is GAME, and I use the term “game” loosely. If you select this, a cursor on the screen appears and as you move it, Fred will follow it. This hasn’t been programmed in yet.
