* Items

* Inventory

* Puzzle objects
  - We need more
  - We need to make puzzles out of them
  - How much state do we save to avoid breaking the game?
  - Toggle switch?
  - Laser emitters and detectors? (Maybe later -- seems like a lot of work)

* Game saving
  - still needs to be worked in

* Enemies
  - One isn't enough

  - Follows from enemies

* Breakables
  - Has implications for saving state

		* floor tile
		* door
		* sensor (1 done)
