Cool game
Very addicting and challenging music game.
There is just few moves with your stylus (everything is controlled by the stylus). Controls are really nice + you get to hold the DS like a book.

Offbeat = Try again.
Easy to learn and it offers a challenge. Definetly worth the money.

Great game
Great musical game, but quite difficult because it doesn't always responds good... Very funny either way!

No title
Simple idea, elegant execution, but look for the game to become quite difficult if you're not too rhythmic yourself.

Like RT, RTG is a lot of fun
If you're even a little bit interested in this game, just buy it. This game is packed with variation and is tons of fun. It'll last quite long too, getting a Perfect on each stage is strangely addicting.

I recommend buying the Japanese version since the dubbing quality of the American one isn't great.

Thanks for the great work Nintendo SPD1 and tsunko!

Rhythm is what you get
This game is just wonderful. Besides it's unique and simplistic -but cute- style, it's extremely simple mechanics makes it a incredible fun game.
It's easy to get the hang on it, even for children (my 8-y-o newphin got addicted to it) and very amusing. The music is very sticky and you have to have good rhythm sense to beat each stage. I think there are around 28 different gameplays, and then hardened versions of some, plus remix every 4 stages. One is better than the other. It can be very hard in some levels, so it's quite challenging!

It has some extra minigames and "rhythm toys" to pass the time. It's even perfect to play a stage or two when you're on the bus,in a waiting room, just fun in a moment!.

Even it got some options to read pure text (the prizes available on the Café once you mastered each stage), you can play all the stages and minigames without knowing a single word of japanese, so don't be afraid of buying it for being in japanese.

Highly recommended!
