if you wan kill turrets, try this room : http://steamcommunity.com/sharedfiles/filedetails/?id=196804170

Definitely looks like a first go at a map. It's pretty intriguing to watch you go from "whee let's kill turrets super-easy" at the beginning to "hmm, maybe I can make the player do a little work" near the end. If you want the map to be about displaying turret deaths, commit to it. Put all the turrets behind windows where the player can't reach them, but can watch them. If you want to make the turrets obstacles, like at the end of the chamber, make them obstacles, and add in other challenges so their death isn't so easy.

Khalvin: Look for a portalable wall a tile up near the end of the first long room.

What exit?
