DISCLAMER: I worked on this game as one of the sound designers and I made the official gameplay trailer you see above (which is bit NSFW).
Lust for Darkness is a Polish horror adventure game, of the “walking simulator” variety. Although it has some traditional puzzles they are on the easy side and overall it’s more like a cinematic experience, rather than something to figure out. Despite easy gameplay, the game is very adult oriented and dark. So… I know I’m probably biased, but I got to experience 90% of the game just as a regular gamer and I enjoyed it.
And here it is on Steam
