I'm about three hours in now. I am what looks like about half way through the "map" on the treehouse wall from which you select levels. Maybe there will turn out to be more than one map. I dunno. And I have completed all the corresponding "bonus" levels that unlock concept art and whatnot. So, I am guessing I am half way through the game. Short game, if so.
The game itself is...odd. I enjoy the puzzle aspect well enough. It's not much of a platformer. It is slow paced. And it is a bit janky in some implementation. There have been a half dozen or so times where I can not see where I am chucking a jelly bean, because it is below me or off screen, and that causes me to have trouble calling the blob back to me. That is a bit frustrating.
Game looks fairly nice, in a gentle, cartoony way. Art style is a bit boring, I find. Music is OK. There's no character development to speak of. I don't really care about the boy or the blob. I was also initially put off that they explained nothing to you as you were figuring out the gameplay.
So far, I find it all a bit "meh". I like Zack and Wiki a lot better, as Wii puzzlers go. My youngest kid (

asked me if it was a downloaded game. Sharp kid. I do feel so far like this game is in the "download" kind of category. Its a bit one-noted in terms of gameplay but I would have happily spent $10 giving it a whirl. But if I had paid $50 for the disc, I would so far be pretty unimpressed. Maybe it'll pick up but, to be honest, I am not that motivated to continue.
I do like the hug button.
