I've now publically cited that I expect this pitch to fail (duh!) given the fund target, time left etc. and even so, the backers have still expressed their belief that the game looks good, and welcome a re-pitch.
I've thanked them gratefully, but it's worth noting here for others to see (such as Silvanis). Just because one pitch fails, it's not the end of the road. If people seem keen on the idea, then keep at it. The trick is to make a re-pitch better or more realistic so as not to bore or disuade the backers and lose them.
More to come...
With your current team, 5000-10000 $ and two month of work you should be able to pull off some amazing trailer or rapid prototype. People want to see, that you have a passion and the will to invest time and money to complete your dream game. On the other hand people don't like the feeling of investing in a 'give-me-enough-money-then-I-will-start-to-make-this-game' projects.
I wish you good luck for the next attempt
