Use turbo mode for better experience. In the beginning of the game, you will get 5 seconds to choose how many human players there are. If you choose 0, it will be AI-only. If you choose 1, it will be single-player, and you will control red with the arrow keys. If you choose 2, it will be multiplayer. Red is a player, and so is blue (WASD) If you choose 3, there will be red, blue and green (IJKL) If you choose 4, there will be red, blue, green, and purple (TFGH) Every square in the background is the color of the player (including AI) closest to them. Whoever has the most squares per frame gets a point and appears yellow. After 100 seconds, whoever has the most points wins.
