You move Goku with the analog stick, jump with the B button, and attack with a flurry of fists and stick swipes with A. Goku also has his signature Kamehameha move mapped to the left arrow on the d-pad. You can only unleash a Kamehameha if Goku has enough energy.
The level I tried was a boss fight against a pudgy pink fellow. Similar to Klonoa, Goku can run a lap around the boss as he tries to hit Goku with his tail. Regular attacks, even a Kamehameha blast, don’t damage him. Laser shooting robots drop into the arena and after disabling those Goku can grab them with the Z button and slam them into the ground which freezes the pink blob. When the boss is encased in ice you can deal damage. If Goku gets stunned by a lightning attack you have to shake the remote to revive him.
The boss was at the end of world two and it looks like Dragon Ball: Revenge of King Piccolo splits worlds into four parts. While Dragon Ball: Revenge of King Piccolo doesn’t have HD graphics, I was impressed by the animation. I think Namco Bandai captured the anime feel in this game better than Dragon Ball: Raging Burst.
