Yes, even a penguin can play the first game to come out of Yuji Naka's new studio Prope - at least if the penguin is good at tapping. You control the game by tapping your hands (or feet) with the wii-mote lying on the same surface so it senses your tapping. Let's Tap seems to be a series of mini-games and will be released in Japan this December.
But Prope aren't happy with this, aiming to make the "Let's" games into a franchise, they are also working on Let's Catch which can simply be described as a game of catch. But games are developed exclusively for Nintendo Wii, with Let's Catch being released as a Wiiware title.
Check out the official Japanese site of Prope, if you're interested and know Japanese...
Now I only need to get myself a penguin for a pet to put Naka's claim to the test...
