This was pretty good!
I enjoyed the atmosphere in the beginning. I was almost expecting a jump scare or two. I also really liked the time-out room and the transition between the facility and the ruins. The puzzles were easy enough to figure out and not get stumped on and it was enjoyable trying to explore and solve how to move forward within the facility.
I only have a few things I would say that stood out that could be adjusted. You did well feeling alone in the facility but I felt the lack of an actual threat. After picking up the knife I expected to fight something. The traps in the ruins were well-placed but I think the movement outpaces the speed of the traps. I think slowing down the movement would help make it feel more of an obstacle because you can just wait for them all to go down and just dash right through at the moment. I would also love to see more puzzles in the ruins where if you mess up something like an order of item placement traps activate and you have to try to avoid them.
Again great submission!
