...here on this website.
I'm pretty sure it was very low profile game (not something well-known like Sanitarium or Stasis). Didn't even have the cover - just a screenshot as its main image. I think it was a horror-inflected mystery game. 2D sprites, but not exactly cartoony. Definitely male protagonist (possibly wealthy), and I think the plot was about him returning to some place after prolonged absence. Some town or a university. And dealing with an old friend who have changed somehow. I can't remember when it was released, but it's probably 2000s.
I found the game randomly scrolling through the site. But that was a very long time ago, and now I can't find it, no matter how hard I look. Can someone please help?
