A fun diversion for a day. The system is just deep enough to hold my interest, but it does become repetitive fairly quickly. The training minigames are probably the most entertaining aspect.
I wish I could complain about the new interface with everyone else, but I can't even see anything besides the background and left-side menu buttons. Can't very well "keep on biggering" if there's nothing for me to bigger.
I don't know, I didn't have much trouble with the jumping once I got a handle on the physics. What disappointed me is how short the game is. I could have done with at least a few more levels.
