I can't see much from the screenshots, but i will download and play it.
Edit:
Things i noticed:
Don't know if it's supposed to be this way, but the crates are
always in the way, so it's hard to get going fast.
Spawn points need to be rotated. Set them away from the base. (see pic) so for the top, it would be
"classname" "info_player_deathmatch"
"angle" "270"
which is "south" in bsp
then for the bottom, do
"classname" "info_player_deathmatch"
"angle" "90"
which is "north".
edit again: oops, forgot to upload the pic
