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 $1.2M — a different platform, not this one.

Cryptmaster

SAY ANYTHING in Cryptmaster - the bizarre dungeon-crawling adventure where words control everything. In the ancient past, four brave heroes banded together to destroy a terrible evil, giving their lives to save countless others. But now their eternal rest has been disturbed by the Cryptmaster, a capricious necromancer in whose thrall they must ascend through the buried strata of the city above them - the gloomy Bonehouses, mysterious Sunken Sea and freakish Downwood. With the enigmatic Soulstone in hand, the four adventurers must recover their memories, solve whimsical puzzles and defeat outlandish enemies. From fishing and card games to bardic rap battles, finding the right word is the key to success. Who knows, maybe you'll even remember a little more than you bargained for...
