Rhythm, music and gameplay. The three factors that makes this game great.
I admire the simple concepts of this game. Simply follow the rhythm, listen to the flowing music and watch your Patapons annihilate every single enemy that will get in your way. If you have rhythm, this is a piece of cake. Take advantage of their fever.
You can see one eyed soldiers complete with arms and legs holding a spear and shield. Funny to think that sometimes they miss, even though their target is nearer. You will also encounter some strange bosses to be defeated in the "Patapon" way, that is, again, following the rhythm.
If you can't get to a level, I can say to you: patience. This game takes time.
