Tips and Tricks
There's a drivable car in the second stage. Turn around after the level loads, go straight ahead until you see 2 warehouses. The car is in front of the left one. A button will pop up on the right of the screen when your goat gets close enough to the vehicle.
Goat can fly only one helicopter, the rest is broken;) You'll find it on top of a hill in the level 1.
