You state near the bottom you are using Unity. In this thread, you stated you originally developed with Stencyl but are looking towards recreating everything in C2 due to limitations. Are you blatantly lying to your backers about what engine you're using?
Also, if you want to actually hit your Kickstarter goal, I suggest removing the 500-backer limit on your $10 pledge reward. Considering 70-80% of your backers are going to be pledging in the $1 - $40 range, having the $10 reward get 'full' could turn some people away.
