Presentation: Menus are simple and effective. No options menu. Background music is cool. Introductory movie is sufficient.
Graphics: Simple and unique.
Sound: Great! Even the repetitive sounds don't seem too repetitive.
Game play: Challenging and long lasting, great for a handheld title.
Lifespan: Still playing it and will be for some time. Multi player would have been totally mind blowing.
Easy to start playing yet difficult to master. Graphics and sound are great. Overall a very unique and fun game. What genre is it? Rhythm-based strategy, how does that sound?
