This is a very interesting concept, made right. The visuals are really well done, it's very creepy. The ambiance of the music really helps with immersion and kept me locked in while playing.
The only issue that the mouse wasn't locked to the screen.
And having a simple loading screen would be good as well. I played it on my laptop, and I thought in the beginning, after pressing start, it was having an issue, but it just took longer to load the dialogue than expected.
Well done!
