Playable Redstone Pacman

This is a game of Pacman I built in Minecraft completely out of redstone. The goal of the game is to get all the green points and avoid getting killed by the red dot(the ghost). To win, you need to get all of the green dots. You lose when the ghost gets you. To move, you step on presure plates.

It works by using quad-way shift registers to move pacman and the ghost. The ghost knowsd where you are, ny telling which part of the map you are on, not the exact pixel. It is programmed in to follow you depending on which section you are in.
