A few little I picked up one whiles going around.
I feel like this is too steep, the player going up here will surly most die as it is very narrow and also open at the top, maybe make it so that the left wall (fence) goes all the way to the top with glass?
this route to last just seems a little to good the fact it leads straight to the point whiles having lots of cover seems too good, to me. Maybe flip it so it comes out to the right?
More visual but damn this building is soo thin is crazy, give it some burgers and fatten it up!
But seems like a really good version! keep it up!
