The experience was unsettling!
The models are really good and the mechanics are explained well. The sounds work perfectly and help a lot to increase the mystery of the game.
You have to be careful with the design of the map. This is a dark game and vision is limited, so you it would be great if you add more distinctive elements in the map to make it recognizable and easier to memorize.
I think the player is too slow. I know that it helps to the "sumberged" feeling, but at the same time it difficults to move across the map. Maybe taking some time to balance the speed or adding tools to go faster could be a good idea.
This was a great entry and the atmosphere was unique. You did a great job!
