Well, actually, I haven't launched a KickStarter project, before, so technically, you're more experienced at it than I am.
That aside, I decided to back your project.
Unfortunately, you didn't think through your pledge levels very well, so I only backed your project for a single dollar. If I may suggest, create some additional pledge levels, less than $20. Because you seek such a relatively low funding goal, this Kickstarter could get fully funded from people making minimal pledges.
The page is better than it was, plus you've posted some updates. You might be surprised at how many people don't post updates.
If I may offer a suggestion, treat this Kickstarter project as though it was succeeding, whether you gain any additional backers or not. Why? Because, it will end up being a much more rewarding personal experience for you, when all is said and done, and you will likely have a better chance of the projecting ending successfully, if you continue to take an active interest in it and continue to grow the project page, including with updates.
Additionally, I watched your video, just now. It's basically a rehash of the text that's on the page. The video is mainly audio, though - audio and a still image of a purple squirrel, one that seems to be moving. Are you holding a video camera or phone camera by hand, while doing the video? If so, then that would account for the movement.
Did you draw that Sushi Man character? If so, then you might want to consider drawing a purple squirrel in that style, and then substituting it for the project image of the purple squirrel that you are currently using.
For a dream about filling the world with purple squirrels, one might think that your project page would have purple squirrels scurrying all about it. It doesn't, and that's one of the reasons why your project isn't making any progress.
There are several squirrel projects on Kickstarter. Have you checked this one out, below?
https://www.kickstarter.com/projects/de ... nav_searchAs you can see by looking at it, squirrels have fans. It's all in how you present them to the public.
Give the public bland squirrels, and you'll likely get no real backing. Thus, give the public some serious squirrel excitement, and the public might just get excited about it.
Also, re-do your project video. Put yourself on camera. You're not gonna do any worse than that static purple squirrel who hogs all of the air time, at present.
You might want to add a map, with states or countries where purple squirrels have been sighted colored in purple. It's really about increasing visual interest, and giving people something of interest to latch on to. At present, there's not a lot on your project page for people to sink their teeth in to, interest-wise. You basically have a core concept - purple squirrels. But, your advocacy of it on that Kickstarter project page is coming across as fairly weak and watered down.
In a nutshell, make it interesting. Don't just have a Kickstarter page - make the page come alive. People on Kickstarter looking for projects to back don't want to be bored. So, don't bore them. Interest them.
