Well done!
I was so engrossed in it that I was afraid it'd be too late for my protection point! That's a very good sign, and a breath of fresh air on the ole portal of crap.
Lotsa stuff to shoot, and it didn't dip below 19 fps until day 21 when I cranked it up to the hardest difficulty. I kinda regretted that >_< One thing that's kind of a bummer is that the fire rates all top out at about the same. Uzi and assault rifle looked identical after about 8 dexterity, and chem and flamethrower fired the same too after a couple more.
And when you use the flamethrower or chem gun at that fire rate the sound effect gets restarted so quickly that it blanks out the speakers like a constipation of audio. Might want to fix it so the sound doesn't restart every time a round goes off; maybe overlapping all the effects at a diminished volume.
Good job!
