Each level has two stages. In stage one you have to reach the castle. Fireballs are shot at you, and you have to either duck under them or jump over them. But the fireballs go at different speeds, so you have to time your jumps/ducks correctly. In stage two you have to collect treasure while avoiding fireballs from the dragon.
