Thanks for sharing, this is awesome! I have never built a base this complex. Really interesting to see how you handled the max-1-per-side constraint everywhere.
Also with BREAM I think you are using the older default settings (spawn every 0.5 seconds, 0.2x pollution consumption). I tried playtesting with those settings and it was too hard so I changed the defaults (spawn every 2 seconds, 0.5x pollution consumption) so congrats on surviving with the hard settings!
