KNOWN BUG: Depending on the order in which the cities are destroyed you may find that as you progress valves give power to the incorrect shields which kinda breaks the game. Unfortunately as I identified this bug after the deadline I can't update this version. You can play a version with just that bug fixed here: https://machinescreen.itch.io/shield-command-bug-fixed?secret=fJgZTvjg2ZOwNy3Eqp...
