Xal Trogg's Mighty War Bubble

You are a minor fleet commander in Xal Trogg's mighty stellar armada and you are tasked with preparing minor world ZX-97B for liberation from the material plane. However, the inhabitants don't share Xal Trogg's mighty vision and plan to RESIST. Our mighty WAR BUBBLE is inbound and you must keep the populace under control! If they grow too strong they will pose a threat to the WAR BUBBLE, this we cannot allow. Tap on your STAR SAUCERS to level the dwellings of the planet, but be vigilant, as the populace will attempt to rebuild.
