Play B.C. Kid / Bonk's Adventure / Kyukyoku!! PC Genjin Online

Hudson Soft released B.C. Kid in arcades in 1989, a time when side scrolling platformers were everywhere. It stood out with its strange prehistoric setting and a hero who fought with his forehead instead of his fists. The game was also known as Bonk's Adventure in some regions, and it had a particular charm that felt distinct from the mascot platformers of the era.

You control a small, round caveman named Bonk, navigating through levels filled with dinosaurs, pterodactyls, and other odd creatures. The main goal is to reach the end of each stage, defeating a boss to advance. Bonk's primary attack is a headbutt, delivered by jumping and diving downward onto enemies; he can also perform a spinning attack in mid air after bouncing off certain objects like flowers or mushrooms. The game moves at a brisk pace, with levels that require quick reflexes to avoid hazards like falling rocks or sudden tornadoes. It feels chaotic and silly, but in a way that makes you want to try just one more time.
