I didn't watch the video, but I read the description. How much do you think you can accomplish in 3 months? 3 months, 3 people, 8000 pounds, that's hardly living money, never mind development costs, and any costs you have to pay for kickstarter for the physical rewards, etc. I wouldn't put my money out for some people who have no track record of delivery, and there's no plan for what will be delivered for the money, or what the end product will entail, what you intend on doing with the product afterwards.

Also, anyone who stumbles across the page sees a project that is nowhere near funding, and doomed for failure. If you can, get a lend of 4 or 5k, and get your family and friends to pump the money into the kickstarter. If it's close to funding you might get enough to clear the goal, and your money back from your loan.

Also, your goal deliveries are october (for early access?) yet your funding is for 3 months? what about the other 3/4 months in between times? What sort of money are you going to spend on marketing the game when it reaches the app store? All this information should be on the kickstarter page. You've also had no updates in the month, which would be disappointing to see if I was a backer.
