I hesitated to leave some suggestions since your game's Kickstarter has already hit the main goal, but maybe this will help you in trying to reach your stretch goals.
The Kickstarter page needs to be more readable for people with accessibility issues. Specifically the story section & the stretch goals descriptions have very difficult to read text & they're on PNG graphics which means I can't use the browser's text zooming tools to make them easier to read or use a screen-reader application. It's important especially because I could not find any directions on how this game demo is supposed to be played. Were the directions on all those graphics of hard-to-read text? Or were they just not there at all?
I hope this feedback helps you refine your campaign.
