Use arrow keys to move blue, W,A,S, and D to move green, I,K,J, and L to move red, and move your mouse and hit space to move yellow. Your goal is to Defeat Black and put him back into Black's Hole. To defeat enemies, hit them with a character, Blue, Green, Red, or Yellow, who has a weapon.
First part of game mainly uses only Blue, but you use all of them. Hit P to open shop. Minor help from Com1236, but mostly made by Rydguy.
