This game hasn't left my Nintendo DS Case ever since i bought it. Its a must buy...
The learning curve is very high for this game actually. I spent forever trying to figure out why i was so bad. I thought that maybe there was some instructions in the japanese that was lost in translation that i was supposed to do. But no, you just need practice. After a few days you will get it down though and the game is amazing.
The game consists of circles popping up on the screen, and you have to tap them to the beat. If you tap them right on time you get 100 pts, a little off, 50, completely off, 0. You have a bar that runs across the top of the screen and when that bar runs out, you lose. Seem simple enough? Just wait until they throw in the ball tracks and the spinning wheel.
The Japanese songs that come with the game that you are playing to are really catchy, and some of the songs may sound familiar, if you watch anime.
The only cons i see about this game is the spinning wheels are IMPOSSIBLE, and last song has an incredibly long intro when you keep failing and have to watch it over, but these are not put into consideration because maybe its just me. You might beat it on the first try! But i doubt it. Haha
Its a great game. You'll have to import it, or go to a store that sells import games, but the best games for the Nintendo DS are the Ouendan Series and Daigassou. It'll be worth your money.
