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.

Evolution

Every 5 Engine levels adds a part.

Home world

The Sabana page has the full map and the flight walkthrough.

Upgrades

All 70 levels, and what each costs. Income costs the same in every world; Engine and Slingshot get steeper each world (see Economy).

The curve is brutal at the top: the final 5 Engine levels are 67% of the whole Engine track. Budget for the last stage, not the first.
