I like it a lot. So far it's the only Wii game next to Twilight Princess and Wii Sports that I've thoroughly enjoyed, and those other two don't count in the first place.
Some of the micro games are hard to pull off sometimes. I don't know if it's my position or what, because I have no problem pulling them off in the practice mode. I've been playing the Mona stage and what fucks me up more is the motion sensing rather than me not pulling it off right.
The "Save her!" micro game in particular. I swear I stick my hand out and the game doesn't recognize shit, but when I do this in practice mode I'm able to pull it off in 1 second.
The game is a great example as to how to implement the Wii remote, so despite these small problems, I'm having fun. I've been trying to beat the Mona stage (can you even beat stages?) but for some reason I always fuck up on the third boss fight.
