This game has plenty of time killing potential. The "killer" is an ad after every round. At that point, you may as well use the multiplier and watch the ad anyway. The catch? Sometimes even after watching an ad and getting the multiplier, you have to watch another ad just to go back to the menu. The gameplay gets to a point where it's nearly impossible to advance without watching more ads to get power ups. The whole game is just an ad trap. Not worth the time.
