This game is, as mentioned in the title, a multiplayer game, so you should play it with a friend. For the unicorn, hit the "A" key to attack the dragon. For the dragon, hit the "L" key to attack the unicorn. The donuts will restore your health if you click on the correct one (the one with your character's name on it). If a character's health reaches zero, it's game over.
Thanks for playing!
