I will say that this is pretty good. The art style is cute, and seeing the girls with various sizes is fantastic.
The only two gripes I have is that the hit box on the bubbles seem to be more squares than actual circles; the detection seems bigger than it should thus latching onto a spot that doesn't really align all the well.
Also, a few times a bubble just up and vanishes when you launch it, which has lead to a lot of early endings for me.
Can't wait to see more places around the world.
