Yo whaddup, I loved this game and I just wanted to give my thoughts on it.
The atmosphere was really good. I think it nails the vibe that the original Mandela Catalogue had and put it into game form accurately while also having its own charm. I enjoyed the audio cues and the mechanics and seeing as it was inspired by fnaf like you said I thought it was really unique and it worked for me
As many commenters have said it was the jumpscares that were very underwhelming. It is understandable to have them because you need a losing condition to have a game but I would like them to be more subtle.
Along with that, I would like to actually see the alternates more. I liked the idea of the alternates hiding in the environment like the one in the bedroom, but I only saw it once in the entire game. It was very scary when I saw it but I wanted more of that to add to the sense of dread I had traversing throughout the house. Seeing them outside windows would also be a nice touch.
Sorry for the long comment, I just had a lot of thoughts. I'm very impressed by this game and excited to see more from you.
