Slick, polished, very well designed. It's a hit, for sure! The retro FPS feel / aesthetic is flawless, and I LOL'd at the story / dialog. I feel like the final boss takes too long to beat, but this might just be due to my terrible aiming skills. You managed to balance out the weapons nicely, but I'm a sucker for a shotgun in FPSs, so I mostly stuck with that =P
