The ads make it unplayable but for a few bucks you can click on "No ads" and get...half as many ads. Then the next day you realize the game is over, eh, it was just a few bucks. That's not the most annoying aspect though. The notifications reminding you to play... don't you hate that. And why does my phone get so damn hot while playing this? The physics aren't that fantastic to justify the cooked CPU and flat battery after 45 mins of playing. Overall, a little fun but ultimately not worth it.
