How do you get the 3 star to kill the bird, because I've killed it in different ways and it doesn't give it to me.

Why are you unable to shoot the birds with your car? The vehicles don't go high or far enough in the air to hit them.

If so, what version of Unity?

I finished the game with 3/5 backflips done on stage 11, now stage 11 is not counting any back flips i do at all. i even tried doing front flips and nothing. it seems once you complete the last stage you are locked out from the achievements. PLEASE FIX ASAP...
