Congrats on making it to the end. I'm also quite in love with how you guys have set up the aesthetic and visuals of your game. The visual distorting as your sanity gets lower was an excellent touch. Also there is a charm that you get from everything being cardboard like cut outs. Reminds me of the bendy's ink machine game that got really popular on itch a while back.
In terms of game play I think the core interactions are solid. I think a good thing to always play with in location type games is establishing landmarks or pathways that establish a pattern of traversing the land so that players feel some reward in figuring out how to navigate. The gun and how its used feels a bit underpowered to me. I get that it stuns enemies but the enemies themselves move quite slowly and are already threatening by looking at them. Also as much as the game is about not looking I think you could experiment with different states of looking at enemies. Maybe distance and how much of the monster is in your centre view becomes a thing.
Otherwise this was really cool so well done again!
