Barring any sort of exploit or error, this should be the last version before playtesting.
Changelog:
Changed out the fence for an actual wall at the lower exit of Blu's second spawn.
Added a fence to the cliffs within eyesight of point B.
Added a one-way door to the mining hut building when exiting towards point C.
Sealed up the vantage point overlooking point B (might return in version A2 with a one-way door).
Increased the height of the wall directly next to point D.
