At first glance level 23 isn’t so special. But the bubbles attached to the ceiling, and after that to each other are somehow not random, there are a lot of single bubbles out through the whole level! The fact that the Black Bubbles are nonburstable is not helping either, so this can be a challenging level for anybody to master.
The tips I have for you is to take it easy and maybe play lower levels to gather coins to buy a Magic Potion.
