No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $24.4K — a different platform, not this one.

Demon Lord Reincarnation

In ancient times, the land of Isigwere was terrorized by monsters led by Leinad, the Demon Lord. His reign of terror ended when a group of heroes defeated him and sealed him deep underground. After their victory, the heroes disappeared, and a maze was built to prevent the Demon Lord from escaping, should he awaken again. Today, the seal is broken, and monsters swarm the maze as the moment of the Demon Lord's reincarnation draws near. Adventurers from all over the world have gathered together to defeat Leinad once again.
