I've given up on Walls. And starting work on a new game. It is with the frustration of figuring out that certain places need to be just in exactly the right places or else the game will not work. I guess I just never figured out the right place for Walls's random code (and psuedo-random code, too.) So I'm working on a new game called Smiley. Basically what it is is AStar for the Odyssey2. I have found the perfect place for everything (for now), and it only took a few hours. So here's a picture of what the game looks like.

The smiley face rolls around happily until he finds the candy cane. I've also made it so he stops rolling once he reaches a wall. The object of each level is to get to the candy cane. I hope to add at least a move counter down at the bottom in the center.
