Honestly I think that you have a great start with it. I would play it. I don't know how long you've been working on it but I want to follow the creation of this. Perhaps if you haven't thought of it already, put it on kickstarter?
Thanks. Yeah we're going to put it on Kickstarter and see if we can get some additional funding. Unfortunately there have been many unforseen administrative hurdles along the way so it's taking way longer than it should. Case and point I've just lost an artist and need to replace them :)
If you're interested I started a blog describing bits of the process. Not sure if it's interesting or not but I thought it might be.
