For it being a free game, it's pretty well done and feels really silent hill-ish. I don't have much experience with the franchise but the psychological horror, using ones own mind against them, being chased by your own horrors to me at least feels like Silent Hill.

You play as a girl in some "villa" that is haunted by a flower demon as I call them, trying to find "something".
You end yourself but immediately find yourself alive again in the villa, unable to escape unless you find the thing.
It's a scary game with decent gameplay and relatively short, around 2 hours. Because it's free I'm really soft on it, otherwise I might have been a bit more critical.

Conclusion:
Definitely worth a try
