Ball of Doom is a game made by Frostblood Studios (not listed on moddb). It features cartoon style graphics, a sense of humour, and Programmer Art? Who came up with that idea, I don't know. Anyway, I will release more content for the game in form of patches, and the level design... well that's ok-ish!
Poor graphics, little to no physics, I actually found this by mistake. It'd make a good game to give to that one friend you hate. It is something akin to Bad Rats or Revolution 60. Scratch that, its a step up from Rev60.
