Suggestion: spectators should also be able to vote on the best submission. You could incorporate it into the formula so there are still bonuses (maybe make it percentage-based), or you could have a separate standing for "crowd favorite". Or you could do it next game. Speaking of which, how many rounds is this game gonna be? Maybe make deadlines 24 hours so it doesn't end up too long and the hype goes away. (only if there isn't another game going on in parallel)
