The title says it all, IMO.
This is a typical bubble pop game, with around 150 or so levels.
My only complaint is that the levels aren’t all that challenging, so I’ve completed the entire game rather quickly. Sometimes I’ll go back and redo a level, but they need to be a little more challenging at the end. I think I only “died” (ran out of balls and failed the level), one time out of all the 150 levels.
