Okay I felt like I was completely at the mercy of the game. And it was a great feeling, stressful and scary. The scenery changes are the ones that scare me the most in horror games. I hated the white character XD the fact that he was looking at me and everything was absolutely creepy.
When the exit disappeared I was like "nope, nope nope no way"
The only thing I would change is the way you interact with objects, especially painting. Because you have to be really close to interact with them to the point where you don't see the whole painting anymore. So you walk close to it, turn around, move, and turn back to check the painting with the text at the same time to appreciate it.
Otherwise I like all the details and possible interactions, the design of the rooms and atmosphere!
