So the start was a bit tough to figure out since nothing stood out on the files, but I found it out eventually. The shooter is actually pretty nice, with three difficulty settings which allow your shots to last longer. (personally the pistol was a bit bull shit with the delay.) It properly escalated in difficulty, and gave you a proper amount of time to react.
Overall, it wasn't especially phenomenal, but the little things it had, makes it stand out for a 2001 flash.
