For ten bucks used, I thought this game was great! I've played it a lot so far and the music's great!
Everytime you pass a level you get some points and then you can use those points to open up secret worlds or play minigames that are really cute. The only one I've played is one where you are making a soup and the guy tells you what vegetable to put into the pot and you choose it and throw it in, it's timed. There's also a little circuit game where you have to be quick in differentiating the a and b buttons in the right order.
You get to jump on levers and fly through the air, float through the sky using umbrellas and jump on spinning air vents, escape from dogs and cats, there's a lot to do here.
I've only played a few hours, and I think I'm about 20% finished. It's been great so far.
For ten bucks, really worth it.
