I spent much of it updating the map to be pixel perfect, but in the end I died of hunger without commiting my map so I played again updated the map again by walking around but ensured I got back sleep and left extra items for the next player. I like the concept alot and I could see myself binging this just by myself to explore the world, though you'd need to have some way to instance the game I suppose.
Though fighting zombies is hard with knifes in previous versions I tried I never really managed to do it without dieing and there are a lot of zombies in areas lol
