Looks really fun in that video. I don't know why I've written this game off until now.
Makes me wonder whether the 3DS is ever going to get stylus-only games in the same vein not, thanks to the 3D screen. Not a single game, scheduled for release next year, will have gameplay taking place on the lower screen. So no matter how much Nintendo fans laud the choice of stylus and resistive screen, no 3DS game will take full advantage of either in the near future.
