Incredibly eerie game. Love the art, which gets ten times creepier when you find the odd lens (is that an Ouija planchette?) letting you see things that aren't there. Also love Linus's character as a depressed 23-year-old NEET who's more ambivalent about eldritch horrors than any normal person would be. There's so much detail and effort put into this, from the interactive piano to the interactive fridge magnets to the Walkman. Delightfully weird.
If I had any criticism to offer, it'd be that like a commenter down below, I found the ending slightly unsatisfying. The general atmosphere more than makes up for it, though.
