Really cool that you did an FPS!
There were so many enemies at one point that I got stuck (in the level after the shotgun drops).
The AK was my favorite gun.
The framerate drops drastically at the start of each level.
Enemies clip through the floor or float above it and can shoot through walls.
The music was really cool when it kicked in.
Ramps being effected by physics fall down when running at them straight-on.
I couldn't tell what the connection to the theme was, since the story didn't play a part in the sections of the game I was able to play.
Great entry, really impressive job!
