Yea, or a hat. The mallet needs to be bigger, more recognizable. It had a darker smashypart that was proportionally larger than currently depicted, for starters.
Re: Inspired by Portal -- I'm tryna figure out whether I'd prefer a clever interpretation on a game title (i.e. Donkey Kong, as previously) or just a nice shirt that uses a title as a general theme. Seems the latter was the winning formula for the previous derbies of this sort, but that to me seems a lot like "draw some things based on stuff".
I guess it's power to the people, at this point. Good thing there aren't many cat games.
