I tested the map out and found one problem.
Players can jump straight off the edge of their alpha spawn and land on the top of the bravo spawn thing.
When they do this, they can jump from the right of the small top right hand triangle surrounding the bravo spawn which is a bouncy polygon, bouncing them onto the top ice polygon of the chute to the right.
You could fix it by stretching the deadly polygon that is beneath the first 3 ice polygons so that it prevents players from jumping on the top of the thing the blue team spawns in... but really, who would have found this out if I hadn't told everyone about it?
Again, the map looks great and the glowing gives the map a warm feeling.
edit: wow, my description on how you are able cheat is very confusing. Here's what I am telling you to do in a more simple way: put a deadly polygon between alpha and bravo spawn.
