atari2600land has started to work on the third part of his GoSub game. It’s a maze/collecting items game.

Release notes:

Work on GoSub 3 has just begun. I hope to make this a 32k game with over 100 mazes, but we’ll see what happens. Here’s where it stands right now. Like I said, I’ve just begun work on it, so it’s not much.
