Flight and distance

The slingshot sets your start, the Engine holds your speed, and you glide as far as they carry you, earning Coins the whole way. Your best distance is what unlocks the next world, and it climbs as you put Coins into the tracks below.

The curve is brutal at the top: the final 5 Engine levels are 89% of the whole Engine track. Budget for the last stage, not the first.
