I can't comment much on the game itself, since everything I know about it comes from the KS pitch. And that's the most crucial problem. Your first priority when rebooting the KS project should be to inform people about the game. When I see KS projects involving first-person shooters, I don't need to see a lot to make up my mind, but with more ambitious projects like PA:A, I would like to know more about it. Don't keep your audience in suspense. Throw in as much information their way as possible - keep the page stylish of course; KS is after all a glorified pre-order platform.
Also, talk about your project in the video. If you don't want to interfere with the main pitch video, you can upload a separate video on Youtube, but regardless, the point is to let the audience know more. Of course you can link everything to your website too - and I'm strictly speaking for myself here - but I'd much prefer to see everything consolidated on the KS page.
PortasAurora: Any suggestions for improving Portas Aurora: Arrival?
Licurg: Lower the price :P There aren't many people willing to spend 20$ on an indie, priced around 10$ or so, it might've done much better.
$20 for a complex 4X game is reasonable, but it definitely has to have a certain standard. I mean, put it this way, I regretted (and still do) paying $20 for Star Ruler, but $60 for MOO2 back in the day was perfectly fine.
