Good, but not great
It was quite nicely put together, although the atcual game didn't really grab me. It sort of feels... like I don't have enough controll over the player... (ie. its more or less impossible to dodge bullets etc, and I don't really feel the movement of the player).
Also, I think it would keep me around if you did not start with all the weapons (that way you always want to find another weapon etc).
Although, it still wasn't a bad game :)
NOTE: I gave you a 5 for sound, as it is an average - as I do not have sound on this computer.
