Every number the game runs on. Saved in this browser; saving restarts the current run.
Drive down the strip, hit 60 km/h before the first row of parked vehicles, and fire the ten floor thrusters to jump the row. The roll thrusters work in the air; on the ground the same keys steer. Gas drains while thrusting and refills while you coast.
Land flat and slow. Hard landings cost health, landing on your roof or hitting a vehicle ends the run. Full barrel rolls score big. The crash-test dummies wandering the strip are worth points if you run them over or land on them.
