Super Mario Kart Xtreme

This is a bit more gory than the usual Super Mario game, but it is still family-friendly despite that.
Play as Mario or Luigi and kill enemies with your Kart. Use the Cursor Up and Down keys (Arrow keys) to move your Kart. Speed up by using the Right Arrow key, and stop by using the Left Arrow key. Press the "A" key to use the Nitro Boost.
