As the newly-established qb label’s first software, it was released with the release of the new portable gaming device PSP (PlayStation Portable). By making full use of the PSP’s 16:9 wide screen, the clear vision and high-quality sound have realized the brand-new immersive playing sensation. The all-new “action puzzle with fusion of sound and light” has come out. The Japanese top music creator, Shinichi Osawa (Mondo Grosso), participates as the sound creator.

The game has been highly acclaimed by the various overseas media: USA Today named it “the best game for PSP”, NEWSWEEK ranked it as the No.1 game, and it has won the “BEST HANDHELD GAME” in Spike TV Video Game Awards 2005. By October 2005, shipments of the game have reached over half a million copies worldwide, in Japan, the US, 17 countries in Europe and Korea.
