So I've assembled the piano and the house from the Labo Variety Kit, and I didn't quite expect either of them to work as well as they've done during my testing. I figured the experience would be closer to something like Wii Sports Boxing with lots of unregistered input commands and the game not doing what you expect it to about 75% of the time. A great product from a quality perspective, though I'm unsure about the longevity.
Now I have to figure out where the heck to store these things.
