Great map, manages to pull of the low-poly look well.
It was very challenging, particularly with regard to lack of health and ammo. This made a couple of sections (falling into a hole and confronting two lava slith in water, and the lava slith spawner in the tower) practically impossible. I hardly had any ammo for my weapons, and the dispersion pistol in its stock state does not work well in tight situations. Much of the time my health was below 20, making some of the puzzles punishing if you fall.
Enough of complaints over combat, it's time to talk about what makes this map great: the challenges.
I was faced with many traps, challenges and puzzles in this map, which make it one of the more unique FPS maps I've played. From the tightly timed jumps across a large pit with only a limited time before the door on the other side closes, to the ride on a round platform over a river of lava, these were well thought out and equally challenging. These gave the map its own feel compared to other Unreal maps, and remind me of the tight platforming in games such as Crash Bandicoot (particularly the temple levels feel similar).
Overall, it was a unique experience, and well worth playing. The combat difficulty issues let the map down a little, but everything else works well.

By the way, I receive a "Can't find map" error at the end, referencing file "UB-FHub4" or something along those lines. Is this map part of a larger project?
