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 $410K — a different platform, not this one.

Knock-Knock

There is an unusual cabin deep in the woods. It had served as a laboratory and a dwelling for three generations of Lodgers. But as of late the latest Lodger has been noticing weird changes in familiar surroundings; things are missing, noises and rattle heard. Something odd is coming out of the woods. Come night, it seems like someone's made himself at home in the twilight of rooms, attics, and cellars. You need to stay awake and sane till dawn. The Lodger is wandering the rooms, evading the unknown, counting minutes till morning. But it's only in the night that he can solve the main puzzle and find the answers. What's going on? Are the Guests real, or are they just figments of his insomniac imagination? What'd happened to the forest? What's happening to the cabin? Is there a line between reality and imagination? Controller support: Knock-Knock fully supports the Xbox 360 controller. Hide! Play hide-and-seek with denizens of your nightmares. Fill in the gaps. The house aids the Lodger. You only have to fix it up and keep it in order. Seek. The Lodger has lost something very important. The reason for what is happening is somewhere inside. Everything that is happening can be explained, you only need to find the key and bring it to light.
