I think I've discovered my latest form of digital crack. Here's an action-rhythm game in its purest form; the execution is simple, never surmounting to much more than pressing a directional arrow or the A or B button, but the music and scenarios are incredibly varied, offering lots of playability. On top of which, the game isn't very forgiving when it comes to judging your rhythmic timing, so it greatly encourages practice to pass and earn higher ranks.
The music and sound quality is almost unreal for a GBA game, boasting crisp instrumentation, and a good handful of vocal pieces. Make no mistake, though -- like Ouendan, the game NEEDS to be played on a sound output stronger than a GBA speaker to be fully appreciated. The Micro's direct headphone output is good, while the DS's is even better. Better still is the Game Boy Player, hooked up to a good sound system. I know I've downplayed the GBP before, but I'd make an exception here, because the game benefits so much more from the Player's beefy bass output.
Is the game import friendly? With the exception of a bit of trial and error for some of the mini-games, as far as understanding how its rhythm mojo is played out, yes, very much so. Most of the games have a helpful tutorial that shows how it's to be done, and even puts you through a quick training exercise to make sure you have it down pat before heading into the real thing. The menus are also very easy to get around, and the mini-game selections are all picture oriented.
All in all, another first class effort from the Wario Ware folks. A wonderful pick up and play title that offers good wholesome fun; it can, however, keep you hooked for play sessions longer than you anticipate.
