I played through this one in a single sitting. I really enjoyed it. Some thoughts:
How would the experience have been better if this map was split into 3-4 separate maps?
I think the enemy density was a bit too high, felt grindy at times.
For me, the highlight was riding the antenna up to the outside area.
Overall, this was a tremendous effort and a must play. Here's my Video Playthrough
. Great work!
