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 $252.5K — a different platform, not this one.

Into the Necrovale

Your fate hangs in the balance as The Stranger, a condemned criminal chosen by the All-Father himself. Preserve this tired world or destroy it, and the choice is yours. The hopeless, the lost, the drowned and forgotten, all must obey one rule: fight to survive. Generations of unwanted criminals and degenerates lurk in the dark corners of the Necrovale. The Necrovale is filled with powerful relics left behind by those whose story ended in the depths. Collect these weapons, armor, shields, staffs, jewelry, totems, hats, books, and other tchotchkes as you follow in their footsteps. Along your journey, you will meet other prisoners. The crimes and failures that brought them to the Necrovale are their own business. Reserve your judgment, however, as you might find yourself depending on these strange and broken creatures to survive.
