Player 1: W and S to move your arm. A and D to move around. Q and E to move your wrist. R to jump. X to kick. Player 2: I and K to move your arm. J and L to move around. U and O to move your wrist. P to jump. M to kick.
Please post in the comments what else I could add. I am out of ideas. Also, if you kick the lightsaber, you're going to slice your feet too XD
