5/5 for the simplicity of the colors and shapes. 1/5 for the screen being 4 times too big.
the 'you lose score:' bug isnt a bug. just press the down arrow, and it shows score.
i would like it better if it wasnt a bat, and it wasnt a target that said click me, and there was no picture in the background. its all very creative, but it distractes me a lot. i do like that you always show the score and high score, but may be make them slightly less prominent. good job though: 3.5/5
