According to ESRB, this game contains: Cartoon Violence
Parents have very little to worry about with this game. While Donkey Kong does punch his foes (often many times in quick successionl), the violence is more cartoonish than anything else. There's no gore, no bad langauge, and no nudity, unless naked apes count.
Fans of the Donkey Kong Country series know the drill: collect bananas, shoot Donkey Kong out of things, and beat bosses. Using the DK Bongos to run and jump and punch makes the standard platforming more interesting, though.
Deaf and Hard of Hearing gamers should have no problems playing Donkey Kong: Jungle Beat. Although sounds measure the player's actions, the player doesn't need to hear those sounds to enjoy the game. Donkey Kong spends his time jumping up walls, swinging from vines and squashing pigs—all things that are done using visual cues. There's no speech whatsoever, and all tutorials use text or video.
