That was both unique and fun. There's something satisfying about popping a big chain of bubbles in a row. I was able to make it to level 4 and that's where I ran into trouble. It talks about destroying the explosive ones first, if I recall correctly. I assumed those were the yellow because they had the same colour as the hint, however I didn't notice anything special about them specifically.
Maybe I'll come back and try again in case I missed something.
Besides the fun and satisfying gameplay I the lighthearted spoofing of 20,000 leagues was pretty entertaining as well.
