They may or may not. I will pose my case and they will likely pose theirs. Levelcoin complies with every single one of their guidelines.
Should the Kickstarter fail, then I will just post the resources meant for Kickstarter, here in this thread. I will then likely use PayPal.
may be so, however it's still likely your kickstarter application will be rejected.
Has there ever been a cryptocurrency Kickstarter campaign?
Not to my knowledge.
IMHO, it would be a big thing if Kickstarter accepts the project. It would give a lot of visibility and provide an entry point for a lot of people who may have heard terms like "Bitcoin", "virtual currency", and so on but remain clueless about how to learn more and get involved. Best of luck to you!
