Pros:

It looks exactly like the Crash series games.
Awsome skins greatly showing how they look.
I like how you made bosses for left 4 dead i dont belive any other map has ever done that.
Dosent cause That much lagg. 
2ND map boss very chalanging on expert even advance.
I can never find choppy stuff. :)

Cons:

I have been pushed into a instant death hole from nothing.
The second stage with the exploding guy nuked the entire map >_< raged my party because it took us forever to get that far.
There has been like 6 times i couldn't do damage to Tikimon no matter what i do Than some random noob the next round after we died kills us all then solos him by one shotting with autoshotgun to the mouth (lots of rages because of that.)
Few times i blew myself up i dont think it has anything to do with the map i was on server im just putting it up here fir just in case i threw a pipebomb away from me and about 10 seconds after it blew up i got killed with Explosion animation that of a hunter(i was playing zoey.)

Conclusion:

Really good map (again some of the glitches could be because of steam or left 4 dead altogether.) Well rounded.
I like having the ability to play a map of one of the first games i ever played. 9/10
