Great game, but I have a couple of suggestions. Mabye like the map room upgrade, what if there was an extra champion cage upgrade? With it, you could hold 1 extra champ in it. There would also be a level 3 for it, so you could hold all 3 champs. But, of course, the upgrades would need to be VERY highly priced, so people couldn't abuse it. If you like my idea, press + so the devs can see! :P
