No offense, but the target of E4000+ is, in my opinion, just way too steep for a game in its current graphical state. They look, and again that's just my opinion, not really professional. Also, maybe, it's supposed to be that way, but the Windows XP setting is ofcourse outdated, perhaps upgrade those graphics to make it more relatable. So to the current Windows 10 version.
So you know, you really got to make a BIG impression, and obviously, if possible, have a reasonable following that will spread the word for you and back you up, if you want to have any chance at reaching the first goal on Kickstarter.
I can't speak from experience, but this seems obvious to me, which is probably why your last Kickstarter failed.
Keep working on your games! :)
