The map looks awesome!!! Great job! But for an original Ice World vibe, a few changes would make it perfect:

Buy zone only in the middle, with buy time lasting the whole round.

Remove game_player_equip — it just messes things up. Everyone should start with default pistols and grab the guns on the ground.

Add more weapon variety like the old Iceworld (include AWP with the others, not in the center, and no Deagles.

If possible, remove the falling snow — looks nice but hurts gameplay.

If you could tweak these, the whole community (and all Iceworld fans) would really appreciate it!
