BlastGuy is a Bomberman-clone for 2-4 Players. The goal of the game is bombing the other players, so that you are the only one left! To gain an advantage over the other players, you can pickup various power-ups.
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
