Of course it has all the same levels and you will probably find 99% of the code is identical but... They have spent time making this app just right, the finger pull back on the track pad is perfect, two finger swipes are awesome, left and right to see birds and pigs, up and down to zoom in or out. You can also pinch to zoom as well as three finger tap to go to pause menu. A quick restart has also been added by just pressing 'R' on the keyboard, which such a good feature. Anybody else appreciate these little things?
