Clear out a few bubbles on both sides of the doom bubbles ASAP, so that the infection don’t surprise you and spread too wide. Then you need to plan ahead, so that you burst as small clusters as possibly, otherwise your score won’t reach a one star amount before you drop the ceiling. Remember the golden bubble Witch Saga Rule, drop big bubble clusters on GREEN spiders! For 3 Star you maybe should save the RB Bubbles to shoot into the ceiling just before you drop the all the bubbles.
