Hey, I just gave it a go, and these are my main thoughts:
Firstly, it would be good if the sound effects altered a bit more as you moved around. I appreciated the buzzing that faded in and out as you went through a corridor, but more variables like that would be good, especially because the main drone stays at the same intensity the whole time. It'd also be good if the sound of Annie's footsteps were a little closer together, and changed sound when you walk on another surface, like the grass outside.
Secondly, the mouse movement to look around doesn't work very well while you're walking. I kept moving my cursor but the view wasn't moving with it. If I wanted to properly change direction, I had to stop walking for a moment to move.
Thirdly, I'm not sure how much this demo version contains, but I ended up quitting because I had no idea where I was meant to go. I seemed to reach a dead end and couldn't find anything else to interact with. If that's just the end of the demo, then that's fine, but it'd be good to mention that on the store page if so!
Lastly, I do think the demo version should contain at least a fleeting encounter with some sort of monster/scare, as currently, you just wander around opening doors and you don't really get a sense for what's lurking out there.
I hope these points can help you!
