Welcome to Open Rhythm!
The Elite Beat Agents's most Iconic Trio: Agent J in the center, Agent Morris with the black hat, and Agent Derrick with the Red Hair.
It's the video game that started it all.
Only released in Japan, Ouendan was a Nintendo DS game where you must tap, slide and spin to the Rhythm and beat of any given song. There are 4 difficulty Levels represented by 4 lead charactors, With the background dancers being largely the same.
This game is rather rough around the edges, being the first installment. But it's completely playable if you pay attention. Having said that, It's not entirely easy. The Music rocks across the board, So you always want to keep playing.
As far as playing with other players go, Yes. But this game doesn't have reply data functionality, So you cannot play against yourself.
