Great, but needs to support multiple users – Medieval Math Battle Review

Great app, but as other users have said it really needs to support multiple users. I have a first and a second grader who both want to play, but the second grader plays it "up" so that the problems are too hard for the younger one. I'd pay for an upgrade that gave you different characters to represent different children.
