Skim the glowing gold zone along the walls to rack up points and build combos. Every close shave and near miss charges your FEVER bar. Fill it and you become invincible for a few seconds, smashing straight through spikes, electric fences and even UFOs.
The cave keeps changing as you fly deeper: from the Ice Cave to Candy Land with swinging lollipops, Buzz Canyon full of bees and the Haunted Castle with swooping bats and drifting ghosts. Wild weather like gusts, blizzards, quakes, icy controls and UFO attacks keeps every run different.
Collect coins and gems to unlock new planes, each with its own strengths: more hearts, faster steering, quicker FEVER or a coin magnet. How far can you go, and how close can you fly?
