I love how you mixed anomoly type games with combat! I felt kinda like an action hero a bit because of the sliding while playing lol. The monsters definitely kept me a bit on edge though. Whenever I heard its scream, I would panic a bit looking back and forth to see where they are coming from.
I also think the red light from the character's back is a pretty clever way to ground and keep track of the player, almost like in Dead Space.
