The music felt a little out of place to the theme of the game. Although maybe it was, I decided to instantly walk through the wrong door purposely 10+ times before actually playing the game. Once the "Your not real" appeared about 3 or more times I continued. Once the music stopped and the game got spooky, I was more into it. I would have preferred if the walking felt a little more responsive. This might because you could not see the prompt until you walked all the way down the hall. I think the game would benefit if the questions and answers were easier to read. Once I got to the "Do you like this game?" Prompt I was teleported out of the room and looking at it from the Unity Void. Not sure if that was by design, but every time I walked to the room, I was teleported back out and then it was eventually gone. Could not do anything from that point and it felt like a soft lock. Not sure if there was an actual ending.
Overall, Nice game. Horror walking simulators are a favorite of mine and it is nice to see how a possible concept played out. Oh, and the mask on popping out on the screen was very spooky, it got me both times.
