'''JD:''' I wanted to take advantage of our machine's color graphics and sprites. A maze-type game seemed to offer interesting possibilities. The logic in [[Munch Man]] is similar to [[Car Wars]], where I was moving the sprites pixel by pixel; I needed the logic to recognize special characters in the maze that determined whether I could go left, right, up or down. This was the same obstacle I had in [[Car Wars]], so I took the main [[Car Wars]] routine and converted it from GPI to 9900 code. That took about a month. Then I tried to design some type of maze that was interesting and would take advantage of our graphics and color.
'''GMK:''' Did you run into any major problems where outside help was needed?
'''JD:''' There weren't any major problems. I only needed help on a few subroutines. No one can be expected to know everything about the machine, so when someone runs into a problem, he'll take a lot of suggestions from fellow programmers because often they have gone through the same thing in another project. In fact, they may already have a subroutine that you can take and just modify. I used at least three or four subroutines that were in TI Invaders.
