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 $0 — a different platform, not this one.

Samsara Room

You find yourself in a strange room. There is a telephone, a mirror, a grandfather clock and some other odd objects you don’t recognise. It seems there is only one way to escape… become enlightened. Samsara Room is a new atmospheric point-and-click adventure by the creators of Rusty Lake and Cube Escape series. This praised predecessor to the Rusty Lake universe is completely re-assembled with brand new puzzles, story, graphics and an immersive soundtrack by Victor Butzelaar.
