Hi,
.) i like the style of this game! nice animations (and flair)
.) it is really repetative, so it feels like you are getting nowhere, even if you are beating your old highscore
.) there seem to be some problems when fighting the people:
they sometimes switch sides
just mahsing buttons will keep you from harm
.)i always just stayed at roof tops, got down beat someone up and went up there again to evade the policeman. But there is not really much space in the top of the screen, it feels kinda claustrophobic up there.
So adding some goals (like levels or hard to reach stars or something) and a few new backgrounds and shifting the focus of the "kamera" a little bit to the top would make this very enjoyable!
