The atmosphere, idea, and visuals all top notch.
The camera could use some work with navigating around environment.
More feedback about the range and distance of the lights would be nice. Mostly guess and check for how far I could move around them. Kept stumbling into the backside of the light and respawning without realizing what was happening.
A count of how many character you need to talk to would be nice.
Adding boundary is necessary in my book (pun intended). Without it and/or a count, I didn't know if I needed to keep moving to find someone. The game let me so that leaves possibility that something could be out there when in reality there isn't.
The way you move through the book and around is awesome.
Amazing job!
