I dig this map. It's my favorite of the symmetrical 1v1 maps submitted to the contest.
Gameplay is generally focused around the Brute shot area, since it's a good place to punish a respawning opponent. The upper walkway ends up being used as a counter position to a player roaming around the Brute Shot area.
Probably my only complaint with the map is the teleporter from bottom mid to Brute Shot. It was essentially never used, partially because it sends you to a high traffic area, and partially because the sender is a little bit awkward to get to. It's a minor complaint though. It didn't really have a negative impact at all.
