I utterly adore this; I've always preferred the aesthetic of the original Resident Evil vs the Remake and having the ability to walk around and explore it in a perfectly recreated 3D environment is just heaven for me.
My biggest complaint however is in it's current state it's just too hard; I'm struggling to get beyond the east stairwell with the limited ammo, no saves or health. Once a save mechanic is put in I feel it'd be a lot more manageable but personally? I'd love a mode that's not got enemies or items or anything like that; I'd love to just be able to walk about the whole game and explore it!
The other things are I'd definitely suggest either having the aim look down the gun's sights or the very least a crosshair to be put in as I often find myself missing my first few shots on each enemy just trying to align where I'm pointed.
