So I played your game and I had shivers. To be honest with you I'm really scare when I play horror games. So each time I heard the sounds of this thing approaching me I was really scare. I couldn't finish it because well.....I was terrified lol. I'm sorry for that. But I tried my best because usually I don't play this kind of games.
It has a very good ambiance, some collision are slowing you and gets frustrating because you don't usually understand what you bump into (chairs collision box are treacherous lol) The monster even though looks simple is just as scary.
I liked the peaceful voice of your player that finds that totally normal. I would have expected a panicked voice to put you in the mood but it was fun to hear that contrast.
For the theme, I was to terrified to understand what the theme was, I just wanted to run away.
Good job !
