This protoype was made in 8 hours (+15 minutes bugfixing) at the January 2012 Mini Game Jam of our Berlin Game Developers Meet-Up for the topic "Future".
In the future, a sport called "Extreme Painting" is all the rage:
Two contestants are equipped with particle cannons and try to color as much of a field as fast as possible, only stepping on their own color.
Each field which has your color is one point, independent of how strong the color is.
But the stronger the color, the harder is it for your opponent to erase it.
Player Left: E/S/D/F, 1 to make your spread wider and yourself faster, 2 to make your paint stronger (you can press each multiple times)
Player Right: Arrow Keys, O to make your spread wider and yourself faster, P to make your paint stronger (you can press each multiple times)
