Thank you for the criticism, I'm tweaking it right now.

in regards to the points individually:
1) I was refraining adding windows due to people camping from spawn AWPing them across the walkway, I think I have a middle ground solution
2) Yeah, I kinda wanted to keep the square tower aesthetic but you're right, gameplay takes priority
3) Fixed with the last point. It was to prevent people from going on the empty side of the tower
4) Changed it
