Wow, this is pretty damn good!
I was kinda echy coming into this, but I liked the FPS, the movements, and the use of sound in this claymation. It was really well done! I especially loved all the creepy grey statues in the middle of it, very great detail and work put into it.
Though things I would improve future works would be background wise, I felt that the background could have been something a little bit more, like a empty black void rather than a stone wall I think would have been a better choice for the scene.
And are you sure about that E? This would haunt many kids for a many days.
