A prehistoric caveman named Dino Riki must survive waves of creatures and environmental threats in this overhead action game, armed with an arsenal of improvised weapons including rocks, axes, boomerangs, and torches. By jumping and shooting strategically, players navigate through treacherous terrain while collecting power-ups that enhance Dino Riki's mobility and firepower—from speed enhancements to wings that grant temporary flight over ground-based dangers. The gameplay demands constant movement and quick reflexes to evade relentless enemies while maintaining enough offensive capability to clear a path forward.
