Chickens is a legendary puzzle game designed and written by Andrei Ellman[1] where the goal is to guide your Chickens safely to the exit through a truckload of mind-boggling and fun levels and if those are not enough to satisfy your addiction, the game also comes with a built-in level editor to create your own puzzles. I contributed the titlescreen and in-game graphics/animations to this game. The game has been in development on and off over the past few years and will go on as time allows. You can always grab the latest public version from the official game page on wackonet.
