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 $50.9K — a different platform, not this one.

Escape Goat

Escape Goat is a puzzle platforming game where you take on the role of a goat who was imprisoned for witchcraft.
