You could deffintly make a full game of this
you should add more levels and such. The shortness of this game is its only downfall. Good choice of music, compliments to Loneroadie on his nice composition.
The game idea is one of those simple addicting games like pacman, tetris, or the original donkey kong. Get 'em hooked with a simple level or two, and as they get further it becomes progressivly harder.
Good game overall.
(If you are wondering about the low overall score, its the average of the other 6)
