After watching your promo video i see why no one is backing you guys. My biggest concern is that you have one shot of a circuit board and around 10 shots of people sketching vases and other cases. The gameplay video could have easily been staged as well.
The controller sounded great until i realized it was a touchpad and not a display.
You're also not asking for enough money for all of the things you want to do and offer by July. You want to do more than OUYA, but are asking for less then half of what they did.
Your biggest selling point is the inclusion of the PLAY store, but if you don't get developers to change the coding for apps than many will not work well at all with your wonky controller, if at all.
For a minute i was kicking myself for not holding out for this, but upon checking your site this looks like vaporware to me.
