Just walked around it on my own, and though I haven't played it with people, I can only imagine how fun it is. It's just super inspiring, all the different areas in it feel really nice. You captured the fantastical minetown aesthetic perfectly, with overhanging rooms and beams and wires, and walkways at different heights. Amazing work! (yes, I know this was made years ago)
I know you're likely not updating it anymore, but some problems I found were:
-Missing cubemaps on the garage door windows in the room outside BLU spawn courtyard
-No clipping on the steps inside Spawn
-A window in the room near the point (RED's side) fades out if you step to the far end of the room. I also think a balcony handrail could be added to the out-of-bounds top level of this building, just so there's no doubt about whether you can get up there or not.
You can get stuck on the inside of this corner, on this clip brush.
Even though you clipped around this metal sheet, the tiny bit poking out at the bottom stops you if you run against it.
I just really love this map, I think it'd also be fun in Arena. Amazing work!
