First time playing, it's very cool. Just finished the tutorial. Everything is messaged really clearly, nice work there. The movement is fun, and everything looks great.
I feel as though games of this type live or die by their level sequence, and as of now it looks like a sort of temporary level select screen. The "tutorial" level itself could comprise about 5 or 6 smaller levels itself. It feels a little eager to teach you the mechanics, and not quite eager enough to enjoy the mechanics. In a mechanic-dense game like Super Mario Galaxy, there's a sort of precision to the introduction of a mechanic. It is taught, and then the player is given a chance to try out the new skill, experiment with it, and get a small victory from having learned it. I think this game would be served really well by such a thing.
At the end, freeing the other bunny from the cage is a great example of this. After beating the tutorial, I felt like I was dropped into a fairly complex level with something I didn't quite understand (a bunny on a stick rotating away from where I was). I want to play some more, so if I notice anything else I'll report back.
Keep it up, this is a very polished and cool game.
