It'd be great to hear from you after you've had a look through the examples and editor. Let me know how you got on and what you think of the project.
Thank you for taking it for a spin. It's good to hear of enticing ideas and experiences. There is lots of potential to create experiences you describe. At the moment there are several areas Apparance lacks before being what i'd call 'game ready'. To move more rapidly in this direction however I'm going to explore Unreal integration of the tech. This should allow combinations of conventional game construction and procedural generation and layout.
