I really like the use of role reversal here, where your cleaning up after the hero. I also love the twist at the end and how it was explained. It would be nice if there were a few more levels to play but I'm impressed with what you were able to manage in 48 hours.
Bug note: If you stand directly in front of the wall in the second level when it falls you can end up being pushed out of the map. Also you can get stuck between the signposts and the roofs of the houses.
