I have been a backer for several Kickstarter projects and would like to share a word of caution for those contemplating being a Kickstarter backer. My recommendation is to first read the Kickstarter's "rules" so that you know what you're getting into when you back a project. If something goes wrong and the backer doesn't deliver or doesn't fully deliver what they promise, you are on your own. Kickstarter does not intervene nor will they even attempt to push the developer to comply. From my experience, I would say that the general tone from Kickstarter is to take the developer's side ("things happen", "developer is solely responsible", "be patient and understanding") versus a more balanced, business like position. Yes, you have the option of legal recourse against the developer but good luck with that approach.
Word to the wise - don't count on Kickstarter to stand up for you as a backer.
