Best tip I can give you that took me a while to figure out...changed the success of many levels significantly...especially times ones. Don't pull back in the sling shot. That takes soooooooo much valuable time. Instead just touch the screen where you want the ball to land and if you want to ricochet the shot,touch it where you want it to hit and bounce from. You're gonna love this. And of course, aim as high as you can to take down as many as possible. Good luck!!
