Will never fail to get your head nodding.
Rhythm Heaven is a series of musical mini-games which tests your ability to follow, listen and groove to the beat of the music in a certain game. When I first saw the game, the interface reminded me of Wario. It looks so simple compare to the ever improving DS games to date. It is user-friendly, with a simple tap, instructions. Practice mode is given in every beginning of a mini-game. An innovation that I've noticed is the way the game is played. The DS is tilted sidewards for it to be played. (Vertically) Also if you're a left-handed person, it has a function to be tilted the other way to be able for you to use your left hand freely.
The mini-games to be played unlocks succeeding levels of mini-games to be played. At the end of each rhythmic game, you'll be given a rating of "Try Again", "Ok" or "Just Ok", and "Superb" and at a certain time or point in the game, you'll be given a chance to "Perfect" that mini-game. This game can be played by almost anyone who can tilt the DS vertically. The difficulty is just right, enough to measure how a person can groove to the beat, I suppose. (Clap..Clap.Clap.Hey!)
