Control the black character with wasd, and the white one with arrow keys. They are on opposite ends from where their controls are on the keyboard on purpose. I'm sorry I am not good at programming. If you notice, when ever the white changes the blacklives, it's not a number. (NaN) I don't know how to fix that. I anyone is good at programming they can remix this and fix it probably. Then If I see it I will put a link in the Notes and Credits below.
