Yuji Naka's Prope game is... Let's Tap
Sonic creator Yuji Naka revealed his new game today at the Nintendo press conference in Japan. Titled Let's Tap, it's apparently the first game the developer's made where you don't have to hold a controller.
If you recall, Naka said the title could be played by a penguin. Now you know why. It appears to be some kind of rhythm action thing where you put the Wiimote on the ground.
More on the game's site. There's some radical music going on over there.
