Really neat concept, letting the player choose their own keybindings while constantly adding new buttons to press! The presentation was quite nice, but quite frequently I got a pop up - new pilgrims, for instance, I pressed the guard button and I got told there was nothing the guard was for. This also happened a couple times with leaky pipes, which was quite frustrating!
Still, excellent concept and a well done implementation! The only thing I dislike was the intro screen - it was too overwhelming with info all at once.
