I was replaying your demo and here are some problems I came across:
1. When I tried to interact with the wooden chest with the head inside the screen went black and I couldn’t interact with anything. I went back and tried it again while crouching and the gun holstered and it work
2. In the final sequence I ran a little earlier than the prompt mentioned and slid a couple of times and that may have caused the demon wife to stay stuck in one place instead of chasing the player, the demon only started moving when I shot her in the head
It may be worth adding these as extra tips on the poster that says E.G. “Pay attention to small details”. Sorry if the text was very long, thanks for your attention.
