This is an a1? It looks like a finished, detailed map.
The majority of the map is flat with very little height variation. At least you put some displacements in...
...except that they're not connected to the ground.
Speaking of the ground, I got stuck in it here.
This is an invisible wall, which is a big no no.
This building looks really cool.
Health and ammo packs just... vanish here...
This actually happens a lot...
I got stuck in this (horribly textured) garbage.
The map looks fine. There's a few bugs here and there, but it's nothing you can't fix.
It did, however, make me hungry.
