Well. It's one month since "campaign" ended. It wasn't successful, it happens. But what is going on with you, mister developer? Not even "thank you" to those 64 backers.
Don't get me wrong, I'm just asking questions. It's not attack, yelling or whatever aggressive... but where is your marketing?
You started with video eating bun like you didn't care you'll succeed or not.
You show something (text, pics, demo) and then you practically told "gib monies"

You were not prepared to Kickstarter campaign! What happened to regular "updates"? Where was information about "future development" with some examples (things not available in playable demo)? And other important things...
It looks like you didn't wanted to succeed. It looks like you wanted a failure to have excuse. I hope you're not...
Talk with some people who knows marketing. Who knows how to make crowdfunding campaign.
I hope your next campaign will be successful. You should make it better or next time I will not pledge at "Executive Level".
Keep up good work. Regards.
