Made a lot of areas more open, mostly.
Changed building extensions off mid pillars back into pipes (but in a different shape) and added a partial wall along it with a grate fence top.
Slightly raised pipe over mid & added a tiny sightline blocker below.
Removed the ceiling and walls towards mid around the ramp up to aforementioned pipe, making it open air instead.
Fixed seeing shadows through the wall on that ramp.
Changed right side route onto concrete to only have one real 'doorway' - Greatly increased the size of or removed the rest of them, making that route much less constricted.
Added a little enclosed ramp from lowground up to concrete, to hopefully allow mini rotations that are much less committal than going up the main curved ramp.
Made the last room of left route into outdoors and moved the ramp down earlier into it.
Changed the transparent tarp texture into a more solid one.
Clipped shutters in garage to prevent hiding stickies in them.
Clipped fences at mid to no longer eat rockets and splash.
Made the curved ramp up to mid much prettier. (Don't worry, it's still clipped smooth into a ramp)
