Congrat`s for you map. It is a very challenging one but it needs a bit more of fine tuning:
1. some long jumps are ... too long, therefore are not possible for all users to make it so try to reduce the distance
2. if you ask me it is a bit too long - 19min for me to finish you map , i suggest you split it in two smaller maps
and
3. i have encountered FPS issues in some parts of the map. Can you tell you system spec`s ?

Here are mine: Intel Core 2 Duo @ 2Ghz , with 2Gb of RAM and with an Nvidia GeForce 9400 GT with 1024 Mb on RAM as GPU

The good parts about your map are:
1. is a good endurance map to bad this game has only single player support
2. i liked those second alternatives
I don`t know if this is your first map but, keep on creating
