1 player controls are A and D to walk, W to jump. F, G and H to attack. E for shinku hadouken. H for hadouken. Space does block but doesn't help at all. 2 player controls are left and right arrow keys to move. 1 or j, 2 or k and 3 or L to attack. 0 or i for hadouken. 1 player is Ryu and 2 player is Ken. Keypad recommended if you want to use the 2 player number controls.
FOR FUN. AS ALWAYS.
