As far as Demos go this was a solid 10/10 for me. Gives you a look at the characters and the vibe the game as a whole. I also really like how it already shows you that your choices matter beyond just being a few different lines of text.
The fact that you can tell that the small horror vibes your getting are just the tip of the iceberg make me more than excited to see just how far things will go.
As far as the game as a whole goes the concept is very interesting to me. I'm really looking forward to seeing how each approach to dealing with Jack plays out. That in mind it'll also be neat to see how your relationship with other characters plays out.
so for anyone on the fence I highly recommend giving the demo a shot.
