Thanks for playing and for the feedback!
I do plan on adding more buildings in the future and it's good to know where to focus on for those.
I hear that on the Hardlight Array second ability. I was more concerned about not allowing an infinite cycle with itself that I overlooked the power costs involved. That will probably have to be scrapped or redesigned.
The powering of buildings & Command Hub are good thoughts as well. Might be worth experimenting with for the next release.
I don't have any response to your other thoughts other than yeah, I can address those. Appreciate every point you raised!
