Erm, i´ve downloaded it... Just copy & paste the Link into a new browser window
Anyway, about the Map, it´s a one-way-run-thru-map
No multiple routes (ah yes, only one on the roof) and tight tunnels...
How about making it larger? i mean, make more routes in the lava zone, the lava bridge, in the big hall ? just expand the map right and left
and the final obj is strange.... u need a lift to complete it... have u thought of liftcamping there? i mean, the defenders can liftcamp and block the whole way to the final obj = impossible to win
suggestion, remove the lift stuff from final obj, make something like in golgotha (yay, but not a heart) with much room around it, etc...
anyway, just my 0.02 cents
