Imagine really fast vertical Tetris combined with Operation.

Nintendo's Japanese website has been updated with a page for a new Nintendo-published WiiWare title.
Surinuke Anatousu, developed by Nintendo and Keys Factory, is a single player puzzle game where you direct a Tetris-like shape of varying shapes and sizes through gaps in the approaching wall by moving and rotating it in three dimensions. The gaps vary in size and shape, and power-ups can cause your shape to change in size. Four control schemes are supported, Wii Remote + Nunchuk, Wii Remote (horizonally), Classic Controller, and Classic Controller Pro.
The game will be released as part of the Japanese weekly downloads on September 7 for 800 Wii Points.
It reminds me of that one game show, I believe it was called "Hole in the Wall" here in North America, but may have actually been titled something like "Human Tetris" in Japan. Looks like it could be fun, I might download it if it were to make its way here.
