This could be really big news. Yuji Naka's studio, Prope, revealed what is likely to be the "Sonic-like" game mentioned last year. And Ivy the Kiwi?, the studio's new game (the question mark is part of the title), has some interesting mechanics: the game uses drawn lines to propel a character, sort of like Kirby's Canvas Curse or Wireway, but lets players anchor one side of the line and move the other endpoint around while Ivy's on it, for finer control of the character's movement.
However, it's for Windows Mobile (or, as the platform is being called in Japan, Windows Phone). Not what you'd typically think of as a major gaming platform. This game is part of a move to change that -- it's a launch title for Japan's Windows Mobile Marketplace and will be out in December.
