This program that I made for my students is clearly inspired by PacMan. Despite there only being two ghosts, I believe that you will find it challenging. One ghost can phase through walls, but moves slowly. The other moves quicker, but is not very clever. The key to this game is speed and strategy. There is no end to this game. The goal is to last as long as you can and get as many points as you can. You gain a new life with every 250 points earned.
