That's seriously a lot of money and dreams lost by a measly 28 bucks. So you can't post the same project twice on kickstarter? I wonder if they tweaked something minor or changed the name would that be viable as a new project?
You can. But if you failed once it really requires a pretty major overhaul to get support a second time around. Most backers will think that if it didn't click the first time there is no real reason for it to click the second time and won't donate.
