A pretty nice rendition of the jam concept, a very crunchy vibe to the whole thing to be certain that is humorous in some spots and a little grating in others. I could see having the challenge be Green Ball has to avoid Red Blocks while collecting Green Ones, and that being vice versa for Red Ball becoming an interesting direction to iterate on this idea, rather than only worrying about the Green Blocks. I will admit it was very confusing that the start screen explicitly tells me not to collect green blocks when that is, in fact, the goal of the game. Still, great job getting something out!
