Really cool dual-wielding system and nice variety of weapons. It's a massive shame I got the Gatling gun just before the game ended! The theme was barely incorporated I'm afraid, melee was pretty powerful, I felt that guns weren't all that required to progress.
It was also pretty easy to snag the player character on walls, not get stuck, just feels like I hit tiny invisible walls. Other than that I was having a lot of fun, and was really disappointed when the game just ended abruptly.
