Multiplayer? Whatever.
You cannot call this a multiplayer game. IT HAS NO FUCKING BALANCE. Ever heard of it? It's when player 1 attacks and moves as fast as player 2. Have you ever noticed that Vortigon is nearly impossible because he moves so much faster than player 1 and his stage moves? EVER? Learn how to balance this shit and it will actually be winnable. Now, last level you basically win out of luck. Pure luck. The level editor is the only thing this game as going for it.
