That was interesting experience to play this, the game is terrifying and I was surprised by it having a sound narration, but, there are issues:
1. scenes lightning is far from ideal, it's dark and have a lot of contrast points
2. objects interaction is a little bit weird because papers occupy the whole screen
3. the storytelling is .. I did not get it, I know it's two sisters and so on, but I don't understand why I need to go to end of the corridor and get back to the start and then stairs appear.. I like the floating bunnies and then it started to be super psyhodelic
4. when I hit Shift protagonist frozes at place, I don't expect this to happen
overall, you did a great job if you modeled and built all of these by yourself, but there is a room for improvements
