Player 1 (Blue shirt) - WASD Player 2 (Red shirt) - Arrow keys Player 1 - You need to touch Player 2's core (the blue swirly thingy) and if you touch Player 2, you will die. Player 2 - Make sure Player 1 does NOT touch your core, (the blue swirly thingy) or you die. If you touch player 1, they die and you win. If they don't teleport back, press the green flag until they do. (I don't know why, they just don't always teleport back)
All by me :D
