This game would get 5/5 all the time if it had good AI.

Lazy developer response, just fix it!
You DON'T need money to play! It's a extra feature! If you can't deal with that, then don't play at all! I've played it without money and i'm level 35 now, and still going strong with nearly all badges.
So many bugs. It would appear you can't fall a great distance, because there is a chance you will just warp through the floor. On another level, I jumped against a wall and i glitched all the way to the opposite corner which killed me in the wall. (Had to press K) My point is, it's a terrible game. 3/5 is me being generous.
