After our initial Kickstarter campaign did not receive the full funding
Bah, I know exactly how you are feeling. Kickstarter is tough in that you either achieve the goal or you get nothing, even though there may well have been many people wanting to contribute.
Reading your pledge levels on your GoFundMe page, it seems a little redundant to repeat rewards at multiple levels, e.g. "Name in credits and website as founder". If you instead wrote them as something like "all of the above rewards plus..." it might read better. Then people have an better view of what additional things they get as they go to higher levels. As it is now, at a level I am having to sift through the list to tell what is new on that level.
Are you considering
https://www.indiegogo.com ? I, and maybe others, tend to associate GoFundMe with charitable causes.
Regardless, you have some really interesting stuff going on. Good luck with your future campaigns.
