We just released an app that allows anyone to make games using just pencil and grid paper -- we call it Pixel Press. IAMA!
Hi, I'm Robin Rath, co-founder of Pixel Press, a company that started with a Kickstarter project (http://www.kickstarter.com/projects/robinrath/pixel-press-draw-your-own-video-game) last year.
We recently released our first game on the iPad, Pixel Press Floors, that allows you draw your own "run and jump" or "Mario" style video game levels on paper or directly on the device screen, customize the design of the level, and then share your creation with the world.
Since we launched a few weeks ago we've had over 1000 levels published to the "Arcade". Many of the levels have been played over 1000 each - and we've seen nearly 50,000 level plays across all levels.
We're also hearing from teachers using the app in classrooms - http://projectpixelpress.com/our-favorite-tweets-from-launch-week/ - something we're really excited to see - and we're currently working on a curriculum to go with the game build around Stanford's Design Thinking Process.
You learn more about how Pixel Press works at http://www.projectpixelpress.com and watch our videos at http://projectpixelpress.com/gallery/floors-overview-videos/
Pixel Press is available for the iPad on the App Store at https://itunes.apple.com/us/app/pixel-press-floors/id847758409?ls=1&mt=8
In the short term we are working to come to Android and iPhone - and we're also working on future games that let you draw other genre's like adventure games and racing games - http://projectpixelpress.com/the-pixel-press-platform/
