Popping bubbles is a classic and you implemented it very well. I do think I found a small bug where one of the blue bubbles got frozen in mid-air, but apart from that everything went smoothly. I kept trying to figure out what kind of placement would work well for my soldiers. Ultimately I just went full on archers and it worked pretty well until my bubbles came down too far. Fun way to mix some extra strategy into the mix. Great job!!
