OK, what's the point
I'm stumped on level 466, so for the first time I looked up the walkthrough. I watched it, and was stunned that that in the walkthrough, the birds were level 8. I'm level 34/35, and get just as many extra cards by scoring 2 mil per level as the walkthrough example get for 100K.
So, everything I've done to upgrade my birds is worthless? The levels increase in difficulty as my bird level increases? WTF? I no longer see a point to the game.
