Hobo Brawl Yayah!
I have some ideas for you. If you ever make a sequel you could make combos like:
Giant Penis Slap, Piss shot, Tiger Ear Wax Tornado and you could put a special bar that, when it is full, you do a super move or something, like, you press D and Mr.Hobo could do a Super Saiyan CRAPtacular Kamehameha!
