Just started playing, not sure I get it…
I'm on level 11 waiting for my energy to restore. I have unlocked bouncy ball and Bomb bird. I two-stared on level 8 and the Red bird just shrugged his shoulders like, oh well! I had over 2 mil points before I got Bomb bird. Then the points seemed to start accumulating from zero again? What's the plane dropping boxes all about? Confused...
