Good luck and I hope to see more from you

A lot of folks here have been burned while helping fund game developers who were of low integrity, and who just milked their followers as long as they could, then took the money and ran (essentially disappeared).
It's much easier to get a bad reputation than a good one. And many who've been burned in the past are going to assume the worst of you when they don't see you measuring up to their expectations.
That doesn't mean they'll never become fans, but you will have to earn their trust. Just be frank about the situation (which I think you're trying to do), and don't sugar-coat anything, or make promises that you may not be able to keep.
Deliver more than you promised, and then you'll start seeing your reputation rise, but it can't be just a one-time event. Do it consistently for several months, and you will see some trust given.
Even then some will hold a grudge forever that you didn't satisfy their expectations one time. Don't let those people discourage you. Most of them have never done anything to make it worth giving any credence to their opinions. Just keep on doing the right thing, and the ones who are worth it will come around.
