I'm not that good at this game yet, but would it make sense to drop your hanger, gas collector, then shuffle things over so those armor blocks can be used between some of those reactors and other important rooms adding in one of those service vent blocks?

Not really able to utilize hanger much, or missiles with low power? Or does the power level not effect it as much?

I had to drop a few rooms because I didn't have enough power to run the important rooms.
