After the war, the city is destroyed and lifeless. A single crow remained among the ruins. In this game you have to guide the crow out of town, stay away from demolished walls and avoid all the bricks. Try to stay as long in the air and pass as many obstacles to gain a better score. If you're familiar with Flappy bird, then you can play very well this version of the game.
This game is played with the mouse only.
