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 $29.8K — a different platform, not this one.

Selfloss

Selfloss is a story-driven adventure game about a kind old man, set in a fantasy world based on ancient Russian and Icelandic myths. Use the light of your staff to defeat mythical creatures and help those in need. Perform a ceremony called "Selfloss" to heal your own wounded soul. The old man hears the cry of an unknown animal and is eager to find it and help it. And thus your adventure begins... The magical staff is central to the game’s mechanics and story. Combat is strategic and dynamic. You control the character and his staff simultaneously and independently: the magic staff levitates around the protagonist, generating spells.  You can explore the world of Selfloss on foot or by boat, discovering Slavic and Icelandic myths along the way as you help others overcome their hardships and grief. A unique sea-worshiping world with whale gods, resembling the landscapes of Iceland. The art style was inspired by postimpressionism, and the colors of Selfloss were chosen with reference to color theories, particularly Simultaneous Contrast theory.
