I just had a crazy idea. A new special brawl mode, Bomb Blitz.
Basically it works like this. The only items that spawn are bombs. If your attack lands, it summons a bob-omb, leading to maximum chaos and maximum epic fight scenes.
But I don't know how to program, so I can't really do it myself. It's just a crazy idea I just had.
