Bonk's Adventure for the Game Boy is a charming and surprisingly addictive platformer. You play as a caveman with a massive head, using it to bash enemies and navigate colorful environments. While the controls can feel a little stiff at first, the gameplay loop of headbutting, bouncing around, and collecting power-ups becomes incredibly satisfying. It's undeniably a scaled-down version of its TurboGrafx-16 counterpart, but Bonk's Adventure retains a cheerful spirit and offers a decent dose of prehistoric fun.
