Impressive demo indeed. During the gameplay, I did forget about this being just a demo, although my overall observation stays the same.
I think the game has a uniqueness to it with the audio and visuals, especially with the exploration of uncanny. However, my suggestions would be that you might want to balance the jump scares and put them further down the line, rather than just after 2 questions. I also think some questions should be more personal and more direct, rather than repetitive and broad.
Overall, great job! Best of luck with the future developments. Cheers!
