Greetings from Germany.
I really liked playing your game, it had some nice visuals especially for unity games and the atmosphere was pretty creepy. I was just a bit confused about the monster. Everytime it appeared I couldn't really see it (I just saw some black clouds in the background) and there was a point where I died (I'm not even sure if I died) even if I didn't see the monster.
All in all it is a really good horror game. :)
