Great furnishing of the environment. It’s a very solidly built set of mechanics to expand upon.
Had some difficulties; the low FoV made it harder to search the scene, and even after finding the letter it was hard to see a key or anything in the barrel, as my own UI was kind of in the way.
Echoing the feedback about the footsteps sounds (would be better not to have any), whereas the weapon swing sounds are very quiet. Some visual feedback when the player damages an enemy and something for when trying locked doors would also be helpful.
