Thanks! In level 2 you have to move fast since the AI is stronger. If it’s not building it’s probably because HQs and Compilers require Injections, which is processed from the Network nodes. I wish I could’ve made the building and input materials clearer in UI but I didn’t have time.
The winning strategy is just expanding fast with the right proportion of buildings (you can check the total production stats of a network in the bottom right corner when you hover over any node). Check out the screenshots for how big your base is supposed to get. I find that 2 HQs with 5 Compilers each are usually enough to win all levels.
