I think I played this one the other day...
Although to be honest, I haven't enjoyed any of the custom maps so far for TF2. I think modders see the simple art style of the game and are fooled into believing that it is easy to map for the game. After logging hundreds of hours in TF2, I've come to realize that every little nook and corner in the map is very carefully considered. The level design is deeply crafted, and planned for the eventualities of anything one of 9 character classes might do in the map, with the scale kept appropriate for everyone from a scout to a heavy.
That being said, this map is more visually pleasing than many, but I echo most of the criticisms about its game play.
