From the introduction:
Slamming the steering stick to the right, you dive toward the Island of Fire.
Crash! You're hit again! Ramda skillfully blasts her macro flash rays as you speed closer to the ground. Dozens of green and yellow fires burn through the tiny isle. Scanning the rocky surface, you search for a safe place to land as Vidi shoots wildly at the attacking swarm of blue ghosts.
