So the main things left for me to do at this point are basically to hook up more UI elements so you can further modify objects in the world. Then, its just a matter of making sure that each element is properly saved and loaded in the level. At that point all I need to do is some additional art and tweaks to the visual design.
I am sure I will be working on additional game play content for Revulsion as I begin taking steps toward a content patch that includes the ability to use this level editor to make levels for the game.
