We used Pixen on OSX for pixel art, and it was really simple to get started. I'd highly recommend it for simple pixel work if you're not a Photoshop guru.
A small nitpick: You have the NES controller plugging into the power button on the first billboard. The controller ports for the NES are inside the black strip along the right side.
Shame your KickStarter doesn't look like it will make it. I haven't seen any press for it anywhere like Kotaku or Destructoid or any of the the major game blogs like Rock Paper Shotgun or 4 Color Rebellion. Any plans on relaunching it with more of a media blast?
We tried reaching out to some gaming blogs, but didn't get a lot of traction. We learned a lot from the Kickstarter process though (blog post?), so if we do relaunch, we'll be smarter about the media coverage.
Keep an eye on our Twitter account/mailing list if you want to see what we do with it. We might go completely open source and just provide build instructions, or we might take another crack at it.
We posted this as a ShowHN recently, but we built http://www.awesomecontroller.com/ as a side-scrolling pixel site.
