Limited fight-based RPG
I don't think this game ends, or at least, has a point. You basically fight the same white brontosaurus again, and again, and again. No monster change (other than size/HP/abilities) and no other activities make this a good platform for a more interesting RPG. I'm up to level78 or something and still waiting for something interesting to happen. Don't get me wrong - you fight the critters enough, you level up and get the requisite tools to do it with. Add a few RPG-type activites to this game, and it's an easy ten.
