Very interesting and fun concept.
l kinda wish the map was a bit smaller, it feels like there's a lot of empty space, The very wide corridors makes it hard to see the walls and figure out if you're walking towards a door or just towards a brick wall. I also wish you could hold more than one item at a time, but that's more a personal preference, I'm sure many others enjoy the added difficulty of not carrying more than one object at a time.
