The Toy Time Galaxy is ace, or at least the first star was. Like Mario does Shadow of the Collosus. Fell off once right near the top and thought I was screwed.
So far I'm enjoying it, but I'm not getting "Best Game Ever" from it, or even game of the year. It has fun levels, but after flying through space and doing cool stuff, I find the flatter, more traditional worlds less fun. Plus, only that Toy Time star, the Bubble one and Rocky Road have really been any challenge.
