I loved the setting and the atmosphere, running out of light works great with a horror game. I managed to finish it after a while, although there were a lot of times where maybe the anomalies were a bit too subtle but I guess it's the point :p Also maybe you should consider adding some sort of fog in the upper area because sometimes I could see things spawning from afar, which defeated the point.
The game looks amazing and has a fun gameplay loop, congrats!
