The controls are easy to use, and the progression follows Abrogation fairly well. The music and SFX were very well suited to the game.
A couple of suggestions for game play improvement:
--Make weapon drops a little quicker to pick up, and less bouncy when dropped. It was a hassle trying to go after a weapon and pounding away on the D key while also trying not to be hit.
--When the player is knocked down, having a brief "invulnerable" period (1 or 2 seconds max) would have been nice to prevent some juggling hits.
