World progression

The game is a fixed sequence of 25 worlds. Clear one and the next unlocks; there is no other path and no unlock price.

• Each world hands you a fresh plane at stage 1 and you grow it there.
• Worlds escalate hard: top speed climbs from 15 km/h to 3,000, and courses stretch from a few thousand units to well over ten thousand.
• The Worlds page lists all of them in order, each with its flight map, stats, and course walkthrough.
