Gemometry and shading are interesting.

The map has many bad points though. An inescapable water pit. A river that runs too fast(flow 0.4). If you attempt to cross it, you are easily propelled into the water pit. Error combo!

Geometry flickers and fades throughout the map (as if it was untextured). I suspect it is the item-limit that is overshot; the map has 610 items.

Conclusion: The visual aspects of the map does not make up for the 3 errors. Rating 1.
