This was fun (always a sucker for combination games), but having the camera shift with every move of the mouse made me seasick. I had to play in small increments, which was a bit frustrating. I'd recommend having the option to lock in on the screen (with camera framing more that the computer to see what's happening in the backstage) and leave the lock to see what else is happening in detail.
Other than that, really cute and with nice, imaginative yet understandable combos.
