1.) Your video is too technical. You may have "dumbed it down" for kickstarter from your perspective, but I'm telling you it's still too in the weeds. People want a very clean demo of the end result, and a very quick and clean demo of how easy it is to use. (Note - your ideal end user may not be the one creating the content - see below).
2.) Consider thinking about your key costumer and tailoring the product to them. If I had to guess, the key market is realestate sales (commercial and residential) and building project management software suppliers, getting away from clunky point-to-point "virtual walk-throughs" (which are lame) into something more First Person game.
3.) I've noticed that a lot of gamers don't realize that most people aren't gamers, so they use gamer terms like everyone knows what they're talking about. Some non-gamer folks have an aversion to the word "shooter". Maybe use First Person Walker?
Bottom line - I suggest you get with a local tech incubator to try and get some free or low-cost marketing assistance to identify your core customer (demographic), then tailoring your product and marketing campaign to that customer. Talk directly to a sampling of your target customers and take their feedback to heart and act on it.
Also, in that process, you should determine if you are selling direct to customer, or what may be better for you - direct to business (i.e. sell your service to larger real estate firms to help them differentiate their higher end listings, white-label your product and have them pay you to tailor it for them).
Who knows, maybe you don't even need Kickstarter.
Good luck!
