The game, developed by Empty Clip Studios, is a music-based puzzle game. Combining the rhythm genre (Judging by the song selection screenshot, it will have indie songs) with a falling block puzzler (It seems to be in the style of Columns, with three-part vertical blocks) it certainly seems like it will be a unique experience. Of course, like most puzzle games, there will also be a 2-player versus mode and a highscore list. This is pretty much all we know about the game - Look at the screens and judge for yourself!
The game will cost 800 Wii Points and, as already stated, will be released in the US in just 3 days.
