I like the idea, but you have a few problems.

First, you have way to many pickups, three of any kind of ammo near each other is more than enough. But you have like three yellow armours near each other. Try to get rid of as much as possible. One thing though, while you had far too much ammo and armour, I didn't see much health any where. I don't know if that's part of the game, but if it isn't you need a little more.

Second, the texturing is weird. You have almost all the light's on the floor.

Lastly, the only indication you give that something is a teleport is a light texture on the floor. I wouldn't complain about that except as already mentioned all the light's are on the floor so it's impossible to know what's a teleport and what's not.

Sorry if I sound a little harsh but that's what I saw.

3/5 for now

Thanks for the comments and for trying out the map.

The reason for the massive amounts of armor/ammo is that in the beginning stage, when the team heads out of the maze, multiple people will be dropping through the armory "tubes" and loading up on ammo/armor. I had to prepare for several people choosing armor as their pseudo "class" before entering the maze, thus the several stacked armors.

The lack of health was intentional. In the flash tower defense games, you kill the mobs, and they have to respawn at the start of the maze. By allowing no health in the maze, I tried to accomplish the same goal.

Lighting on the floor...I could change that. I tried lighting from above, but I didn't like it too much, maybe I can play with it a little.

The teleport thing might see a little odd, but I think if you run though a few times, you will see the way I used colored lights to represent the destination of each teleporter. I also placed ammo inside of a clip box to indicate what you get at the other end of the teleporter. Of course, since I designed it, it all makes sense to me :) Stumbling in the maze the first time it's probably not so clear.

Thanks again for the comments.
