This is another version of Super Mario adapted for Flash. This game looks and feels exactly like the original Nintendo game, and as far as I remember, the levels are the same. You can choose the controls you want to use. If you don't change anything your default controls are: A and S to walk left and right, S to crouch, 2 on the numpad to jump and 4 on the numpad to launch a fireball. To make 2 and 4 work correctly, you must enable the NumLock.
