Patapon 2, Action game by Kerb.

Become a Warrior God, amassing a Patapon army! Victory will be judged by the number of Patapon characters collected.

Your left arrow key plays 'Pata', your right arrow key plays 'Pon'. Follow the chant of the Pata Pons by pressing the correct arrow keys to the beat of the drums. Tap out a command, wait for them to repeat it, and then tap it out again to keep the rhythm going.
