Spelunker

Spelunker is a cave-exploration game ported to the Famicom in 1985, notorious for its staggering death rate. The protagonist is almost comically fragile — a drop of even modest height is instantly fatal — earning him a legendary reputation as gaming's weakest hero. Players descend through multiple cavern floors, collecting treasure while managing a limited supply of bombs and flashlight energy, using flare guns to ward off ghosts, and monitoring their oxygen. Despite its simple platforming appearance, punishing hit detection and strict resource management make every run a genuine challenge, and the game holds a special and enduring place in Japanese gaming culture.
