User Rating: 7.5 | Alvin and the Chipmunks DS
The game IS short, won't argue with that, but from all rhythm games this is the only one which i liked every song in the game. The gameplay is basic, no one should have trouble in playing, though sometimes it seems a little broken (long notes only), the audio is good, which is essential to a music game. The only thing it's a little uncomfortable is that the game gives a look of "made in a week", it didn't have a proper story or ending, nor extras, but i still think it's worth for the songs.
Overall, if you like the music of alvin and the chipmunks, you WILL like this game, if you don't like, then it's a waste of money, go buy an Elite Beat Agents.
