Remarkable design, eerie atmosphere and intriguing story - one of the best demos I've played this year!
Now, before the review, I should say that I really love the dev, their content and whatever they make is great. With all that said, I think, objectively this was a fantastic demo. The game has superb sound design, high immersion level and it is well optimized, which is rare for UE games. I can't wait for the full version to come out soon!
The collision system and some of the dialogue can be improved as well as the overall story, which can be expanded, but that's just nitpicking and nothing else.
Best of luck with this project mate!
