Having played the TFT boxed labyrinth *Death Test* I'm very tempted to say that Steve Jackson isn't a very good scenario designer. Interesting classic, but when there are no other options than fighting you just shut it down without even a dice roll, you should have done better.
Also, starting all enemies in the centre of the room with just so much movement that they if they win initiative will be able to block you from maneuvering, that's just lazy and boring.
