Use your mouse and keyboard to guide Roxton through the volcano's searing hot passageways. Click on your left mouse button to make Roxton rise, and release it to make him descend.

Pressing the V key on your keyboard will make Roxton speed through the tunnels and past obstacles, while hitting the C key will put on the brakes and slow Roxton down.

Keep an eye out for bonus gems you can grab, and dodge the bombs, flying rocks, and other obstacles that stand in Roxton's way.
