This is the last version of the game, using the right player, you can practice against an enemy. I may script a more random enemy so its not simply spinning its swords, but you can change that any way you wish.

Player 2:

Go Forward = Left Arrowkey
Go Back = Right Arrowkey

Sword Up = Up Arrowkey
Sword Down = Down Arrowkey

Left Sword Up = PageUp
Left Sword Down = PageDown

I say player two, because you are playing as the dude on the right.
