Cubes Challenge

@hiimfloyd one of my friends who is color blind said he couldn't make sense of it during beta. I have never done anything of the kind I would need to see how game mechanics would work for the color blind. - Promise though, 1.1 will definitely have color blind support!

@myusuf3 @hiimfloyd Until then! Looks cool -- just can't tell between green and red. : )
