This level is impossible to pass. There are never bubbles of the right colour, especially if I'm fortunate enough to reach the top. Also, it means the frozen (?) bubbles spread and you don't have enough moves to keep popping them. And why are boosters so hard to get in BW2? It's quite a mean-spirited game tbh, especially compared to BW3. I've noticed that levels are often changed (you can tell in the videos) to make them harder, which is really unfair after some people have passed the easier versions. Anyway, games cease to be fun when levels are made impossible so I'm pretty much done now, and it's a shame so early on.
