Not too bad
I am actually going to say that was alright but quite a few things grated on me (major problems):
1) Firstly there should be better music choice or a button to mute the music because it was not good.
2) The movement could me smoothed out and also the graphics aint too sharp.
But apart from that all the rest were minor details - perhaps adding a map or something?? Or a slight hint at where you are suppose to be going???
