Thank you for your message! I'm glad you enjoyed it :)
Also you found one of my personally favorite strategies (though I'm still not sure which one is the best one yet).
You are totally right, we had a couple of extra ideas that we didn't make in time (for buildings and mechanics). I so wish we had more time to test and work on those. It also meant balancing questions, like ideally no building was a huge power creep compared to others, and we were scared of "breaking" the game with some OP building.
Thanks a lot for your feedback and kind words!
