Can’t you just make a start on some of the elements of the game yourself, while you are waiting to get funding?
What is your skill set? Are you an artist? Programmer? Level designer? Composer?
It just seems a bit strange that you are asking for funding of an idea, with no tangible proof of a game.
I can’t imagine your crowd funding will be tremendously successful without a little more substance. I have seen nearly fully fledged games fail with crowd funding.
Sorry if this is coming off a little negative, I am just a bit bemused by it all.
