It is on Wii. You have to use the sensor bar to aim your paint and thinner, but that's not too terrible an issue. The biggest problem I have is that it takes a bit of effort to reach the pause button. And the camera could use some work, but that's not so much Wii-specific as just a general complaint.

I want to play Kingdom Hearts, but last time I checked I had all the wrong consoles. Maybe that's changed ...
