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 $7.9K — a different platform, not this one.

Cult Vacui

Cult Vacui is a point & click with survival horror elements,  set in the late 19th century on the remote island of Barra in Scotland. We play an unsuspecting janitor who has been given a job opportunity to maintain the Gladstone family's summer estate. What we discover is that the day before we arrived, a gruesome blood ritual was performed on the island's population at the hands of a creepy cult.    A RACE AGAINST THE CLOCK Our arrival has ruined the ritual, which can only be considered concluded if every person in the perimeter of the island is eliminated.  Apparently we are their last obstacle... at least that is what we believe.  We have a few hours to prepare for the last act of their insane ritual; we must prepare a strategy to defend ourselves and (hopefully) survive.    CREATE YOUR OWN STRATEGY In Cult Vacui, every choice counts, every action we take takes time that will fall short of the final act countdown, find the right strategy to maximize your efforts (even across multiple game sessions).   FEATURES Logical but challenging puzzles, apply the right solving strategy without getting frustrated your every action consumes time, in a countdown to the final act creepy horror atmosphere multiple endings based on your game choices Pixel art graphics handmade and thought by a real human being Engaging and original soundtrack composed by Ascari, a musician also credited in film
