Sound and music play a huge role in the game. It's like a traditional rhythm game, but completely different. Instead of watching the screen and jabbing at the buttons that match a bunch of scrolling symbols, the interface for Patapon is 100% clean. You'll actually have to listen and "play" in time with the beat. There is a flashing frame that serves as a visual metronome, in case you have difficulty following along by ear. There are definitely moments where the game throws you a curve ball, either with some event in the background (lightning/thunder) or exhortations from your Patapon warriors. In these moments, it is easy to lose track of the beat, which is a big handicap. Keeping the beat going is key to succeeding in the game. Proficiency in performing the different rhythms is really your interface with Patapon, but you'll often feel like you are just a spectator on the action while manning the drums. Through much of the game's early stages, only a few unique beats are available. Until you have opportunity to mix the beat up and control your Patapon army with more precision, you'll feel like a cheerleader with only a few cheers at her disposal. It doesn't take away from the fun, because you still feel like you're controlling the action, but it grates on people that aren't actually playing the game. Get your headphones ready for this one!
