I got a score of 15495.
The chicken is offset from the mouse and can go off screen down, but stops before he reaches the top of the screen. I think that the chicken should be centered on the mouse and have to stay fully on screen.
Some background music would be nice to keep the player engaged for longer. Also the speed of the bombs should go up the longer you go. Right now you can pretty much go on forever. Another thing that would be cool is different kinds/sizes of bombs. Maybe some that do a wave movement for example?
