I finally got around to playing this, and I think you did a good job scaring me! While although the scares came via surprise sounds and ghostly figures, I did like some of the effects you pulled off. The ghostly shadows of the fast zombies, were cool, and I liked how you had the player go down this hall and return only to find the hall change to a different space all together. -That was pretty neat.

The map lacks a lot of detail, but I'm guessing since this was one of your first maps, you seemed to focus on getting across the surprise factor. Which I think you pulled off fine. There was one major issue I think you should fix, and that, I think players should have an item_suit from the start of the map. It's really hard to see in those dark spaces. And, it gives some comfort in the horror.

Other than that, I think you pulled off a scary first map!

Keep it up
