Envelope Drift

Envelope Drift is a side-view hot air balloon game built on a real flight simulation. There is no steering wheel: you climb and sink to find the wind layer that carries you where you need to go. BURNER, VENT, DROP Hold the big Burner pad and the air in the envelope warms up, gets lighter and the balloon rises. Let go and it cools. Hold the Vent pad to come down faster. Tap Drop to release a marker bag over the target. READ THE WIND Every height has its own wind. Some layers carry you down the course, others push you back. The wind ladder on the right shows each layer's direction and speed, and the course strip at the bottom shows the cross, the finish field, obstacles and where your marker would fall. SEVEN REGIONS Fly a journey route across Tulip Lowlands, Vineyard Valleys, Alpine Pass, Desert Canyon, Rice Terraces, Fjord Coast and Savanna Plains. Each region has its own scenery, terrain, wind and obstacles, and further regions open as you earn badges. OBSTACLES Clear oak trees, poplar rows, power lines, church steeples, windmills, rock spires and radio masts. Keep away from rival balloons, storm cells and bird flocks: they damage the envelope, and a damaged envelope loses heat faster. TARGETS AND THE FINISH FIELD Twenty-one legs in three kinds: drop two markers, land only, or drop one marker and land. Earn up to three badges per leg for hitting the target, landing in the finish field and bringing propane home. HANGAR AND RANKS CP earned in flight buys four upgrade lines: Envelope, Burner, Vent and Wind Probe. Rise from Cadet to Pilot, Captain and Master Aeronaut, and keep every flight in your Logbook. PRACTICE Fly any region with your own wind strength, no records kept. OFFLINE, NO ACCOUNT There is no advertising, nothing to buy and no sign-in. The game works without an internet connection and your progress stays on your phone.
