Don't get discouraged about the few responses. Not everyone is interested in every type of demo, and most forum participants won't log on simply to say "me too". I think you should take the response as favorable.
I would be interested in any hints that may help to develop a system such as yours. Of course, if it is basically the same as in AUM, then The need for it would be minimal, but any new ideas would be helpful, indeed.
I hope you are able to finish the game and that it's a great success.
Happy New Year!!
