Hi! I have just released the source code for my game "Be2 - Escape from Pingland" and its level editor. It was featured in the "News & Noteworthy" section of the US App Store and many others. Do whatever you want with it. Just say "Hi!" to me if you find it interesting! You can find the source on GitHub. You can download the game from the App Store. More info on the Kismik web site. Have fun!
