Too many ads. You know a game is bad when it interrupts you during a level to play an ad. At first I thought I had accidentally clicked on a banner ad, but nope it was an ad that just played automatically and took over the screen. Not to mention that when you finish a level you get this weird bonus bar where you can get a bonus? i guess? if you watch an ad, but if you choose to disregard the bonus, you're stuck watching an ad anyway. Not worth your time.
