MaKey MaKey Super Mario Bros
You can use the regular controls, but it is more fun if you do this with a MaKey MaKey. You can order MaKey MaKeys here: http://makeymakey.com/
Use the arrow keys to move.
IF YOU ARE USING A MAKEY MAKEY:
You need to hook up the arrow keys and space bar. Make sure that you have your "earth" attached.
Thank you to @PaulKoning for making the original project.
I want to make it very clear that I am NOT the original maker of this game. Since I shared this, the original game has been removed, and I guess this has become the new "original". But I am NOT the original maker of this game. That credit goes to PaulKoning.
