Use WASD or arrow keys to move and space to interact. Press Z to teleport back to the start of the level. If your health reaches 0, you lose. The characters are generated randomly, so there is a chance of winning early. If you are having trouble with a level, just interact with the area you spawn on. For the full experience, it is recommended that you don't do this.
