K. i played the entire thing with all the textures and let me start by saying this map and the scope of the entity work is huge. This must have took you a long time, or at least it would have taken me AGES to complete! = )

++Grand scope of map and project
++Superb entity work (traps, sequences, mechanisms and contraptions)
++superb detailing and very neat ideas
+Good brushwork
+Decent lighting though a little dark through most of it
+good sounds
+good effective use of sprites 
+good use of original textures and i loved the confusion room hammer-like ones, specially the water = )

-nothing really flows together, it is a great amalgamation of differing trials. Too random and convoluted imho
-way too long (though i appreciate the grand effort into this
-no autosaves
-sometimes no logical or clear way to proceed (or i am retard which i am)

This map is epically big, and there are many pretty and interesting things too look at. Though i wish the map had a more congealed, central theme, there was still much to admire. The theme you set reminded me of a deserted black mesa or close cousin, and some of the industrial/service-looking pathways gave me the feeling of portal a little bit. Some really neat trap ideas at the end that reminded me of Hunter's 5-ways to die, and some very cool, new stuff that reminded me of nothing i've seen before.

All in all, a grand effort and it's obvious for anyone who's gone through the map. I look forward to seeing more stuff from you, and i hope your next project has at least a quarter of the dedication you put into this one. As your skills get better combined with this, your maps will be epic.

As previously stated, 5 stars.
