Control the blue crow with arrow keys and fright away the sparrows trying to peck the treasure being kept in the center. With the time going on new sparrows come in and get bolder and bolder. You can't just press a key to make the crow moving, you have to press and release the arrow keys.
Today I walked to my office and saw a scene on a lawn. A crow guarded something laying on the grass while pigeons and sparrows surrounded it and kept on trying to steal it. It was interesting to behold but I had to go. Thank you, birds, for giving me inspiration to make such a game.
