Did not play it, did not rate it. But reading the concept, this might work a lot better as a play in browser game. Not necessarily the effects, but willingness to play.
I for one would not download a "os" from an unknown source. Not that I would think it is a virus, but let me put it another way. Some dev makes a game with ... horror elements that are possibly breaking the 4th wall. Some of those effects I might not want to have on my computer. It is a thing I might try out in a sandbox, like playing in browser.
Also it is suspicious that the setup.exe is smaller than the zip. I have played dozens of games from itch. Not a single one of them had a setup routine.
In an unrelated note, one of my favorite games is Eternal Darkness on Gamecube. Boy did that game eff with the 4th wall when sanity was low... ;-)
