Not too bad.
It was rather good, nice graphics, but the music got annoying after a while and the game was very repetitive. Adding more stuff to it would help greatly, more weapons, power-ups, moves... etc. The controls could also use some improvements, such as being able to go back (To get the money =p). I got 158 gold on my first try. =D
Work a little more on it, but you did a good job. =3
