Looks nice, I've tried it only playing alone, only to explore the map.

But there is one "sky door" without teleport, and one "teledest" (the sniper one) with no corresponding teleport.

For me, it looked very creative to create those glass towers.

You have to explore a little deeper to find the teleport into the sniper box. But be warned, if you get into the sniper box the only way out is to die.

it's hidden in the wall underneath the sniper

And that Skydoor without a teleport is a trap. You walk into it and you're like "oh crap" then you turn around and BLAM! you're dead. As said, this map has a few Tricks and Traps.
