Khufu-ou no Himitsu

Khufu-ou no Himitsu is a role-playing dungeon crawler developed by Kou Shibusawa.
Players assume the role of an adventurer who seeks to discover the hidden treasures of King Khufu inside an Egyptian pyramid. Gameplay consists of exploring labyrinth levels filled with mummies, spiders, and all kinds of creatures; running into them reduces endurance points. The protagonist dies if their endurance is fully depleted or if they neglect to consume food rations.
