Press X repeatedly to fly upwards and hold X to hover. Use the Arrow Keys or A or D to move. Your goal is to reach the flag in every level, but keep an eye on the meter on top of the screen. That's the energy you use to fly!

Some levels will require a longer journey to reach the flag. You can recharge your energy by hovering at the yellow flower to drink the nectar. Make sure you avoid the enemies and elemental obstacles to get back to the outside world.
