I would be approaching Kickstater with what you have said above.
This is what kickstarter have to say "Kickstarter’s Terms of Use require creators to fulfill all rewards of their project or refund any backer whose reward they do not or cannot fulfill. (This is what creators see before they launch.) This information can serve as a basis for legal recourse if a creator doesn’t fulfill their promises. We hope that backers will consider using this provision only in cases where they feel that a creator has not made a good faith effort to complete the project and fulfill."
