All I advise a developer is to do Q&A, because it's not clear why development is taking so long, if you say there's only two of them, they can't do everything so fast, I'll let you all in on a little secret, it's rare to find developers who have people doing both rendering and code, most of the time it's ONE MAN!!!!, most of the indie companies are one or two developers, because not many people will work for free. All I advise Inqel, create a Q&A and try to find helpers, I'm sure even here there are those people who want to help out
