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!
20 Missions, 10 Skydiving levels and 1 Superhard mission comprimise this full release of Ball of Doom.
