Pros:

This is AMAZING
The Music fits perfectly
Whenever it comes on, it actually can scare you
The music is tense and atmospheric

Cons:

Don't take this as the music is too quiet because it isn't, it's a nice volume but more volume would be so much better as it would add to the atmosphere and make it a lot scarier

Conclusion:

An Amazing Download, a Must have, perfect song

Pros:

Amazing Fun
Challanging 
Very good job 
Reminds me of Crash Bandicoot :D 
Boss Fights are Challenging

Cons:

Too High spawn rate Partically Level 3
NPCs run into penguins and other weird creatures killing them
Not enough health kits
NPCs are useless against bosses

Conclusion:

Great Map very challenging but do it with friends I did it 2 player and the NPCs were useless definitly a map I wouldnt try Expert on:P Recommended 4 player, Fun and Challenging
