You need two players!!! player 1 arrow keys to move, press k and l to move sideways, press p to shoot. Player 2 WASD to move, press z and x to move sideways. Player 2 must survive until the time is 0, and player 1is trying to demolish player 2, in the middle, their is a secret house and only player 2 can go inside, but player 2 can only go in for a total of 1 minute, or else player 2 will lose. You can only enter through the red portal, don't try to go through the blue on, it is useless, also player 2 is faster than player 1.
