I really like the demo, this is exactly my kind of survival horror. I like the setting, the mood, the lighting is nice, the way you use music (and then use NO music for specific moments) is great. Looking forward to playing more!
My only actual feedback is more UX related stuff, like when you're interacting with a medicine cabinet or the item chest, simply pressing a button on the item should be enough to move it into your inventory or out of it, I feel like having to dpad the selection all the way to the item, pressing a button, and then dpading the selection over the other way to your inventory or the item chest area, is going to get old pretty quickly.
If you can also add some way of moving only some of your ammo into the chest, like splitting the ammo or selecting an amount of ammo/items in a stack to move instead of the whole thing, will be nice going forward.
