Very quirky, very awesome
Came across this game randomly on Play-Asia. Had to get it after I read about it. While no Japanese is needed to play the game, it takes a few minutes to get used to the menus, but once you do, it's all a breeze. Great gameplay, think Warioware meets rhythm game. It met all my expectations and more!

Worth to get
If you like 'wario ware' style games or Rhythm games in general, you really can't go wrong with RTG. Starts simple, but grows progressively harder, it will keep you buy for a while.

Best of all its one of the more friendly titles for the non-japanese speaker - If you played Ouendan (without being confused) then this should not be a problem.

Brilliant!
Wackier than Ouendan an it has more reliance on actual musical timing than just speed, so it's harder too.
Brilliant and highly recommended.

Very fun
Similar to the first game. Touch screen makes it more challenging thus more fun as the first game was a tad too easy.

Very Import friendly if you don't want to wait for the English version.

Quirky, yet awesome.
This will get you hooked with the crisp visuals and the simple mechanics. Quirky presentations and great music makes this a one of a kind rhythm game, if you never played the first one, this is a great time to start getting addicted to the Rhythm series.
