Construction was simplistic, but well done, on this map. It's next to impossible to get lost on this map, as it's just a staircase going up and down. The level consists of two bases, at either end of the stairs, and command points thrown in the middle of the staircase. I didn't notice anything in particular about a smokestack in the map, and I'm assuming that the author meant for the map to look like one. It loses points for theme there.

Teleports were used in an attempt to speed up gameplay.  Unfortunately, though, you never really know where you're coming out. Arrows were used to tell you which direction you're going, but you don't know how far up or down you'll move.  When trying to get from the top to command point 3, it can be quite frustrating to jump in a teleport only to go past your goal.  And since there is never more than 2 ways do anything, this map can get boring quite fast.

Due to the guarantee of a confrontation, teamwork is a must if you want to score.  This is one area where this map shines.  A scout can rarely make it all the way down (or up) the stairs without a some assistance. Quickly being able to set up a make-shift defense at a command point is also very helpful. Unfortunately, this type of teamwork is rare on public servers. Canal Zone 2 strategies almost always apply, but with no where to safely place a sentry, a defense can be hard to keep up. Due to the spiral, snipers were near useless.
