Press A & D to move Godzilla. Press Q to attack King Kong. Press the right & left arrow keys to move King Kong. Press space to attack Godzilla. This game is two player only, but I will make a new one that is one player soon.
The original one by @gamerguy2 had one problem, he set it so that Godzilla couldn't die so I fixed that, but his game is still really cool. Edit: gamerguy2 fixed his original, check it out! I'm planning on changing this one drastically.
