I know quite a few of us are jaded because of people promising the world and delivering nothing -- people never realize how tough or time-consuming game development is until they try it -- so we tend to take game announcements on galleries and forums with a grain of salt. It looks like you have your ducks in a row, so to speak, so consider me as both an eager watcher and another source of help with Quest and its occasional quirks (like how and why Quest occasionally forgets with the "this" keyword means... Quest's scripting language isn't quite as bulletproof or mature as Java is).

As an FYI, there is a thread on Eka's that lists vore games that people made in Quest and similar engines, and exploration-based games are about as non-existent as you think, so I'm definitely looking forward to this. When you do come out with a version, even a demo, I'll make sure it gets added to the list; that will at least add to the number of people who are aware of the game's existence significantly.
