As someone who has helped with indie campaigns previously, I have to agree with basically everything Shoeberto is saying.

I'm not certain how you expect to generate a following or buzz when you don't have any content to show, but just a concept to share. Sure, it sounds like it could be a cool idea, but outside of an idea, no one really invests in an idea. People invest in what they are shown, and growth.

A dev blog would be really helpful, just to get a better understanding of concept AND a better idea of when you can post screens that things like that. Even little teaser pics of a title screen can go a long way.
