I saw your game on vinesauce's stream, and as a lover of retro fps games, I had to check it out. I really liked it, but there was one issue: I was able to cheese the last boss on violent difficulty by continuously (wall?) sliding on top of one of the corner pillars. I was scoring headshots as they kept trying to charge into the pillar. That's a shame, because I really like the challenge of the encounter and how it jumps up halfway through.
