Click on different active elements : engine, rudders and air tanks, in order to navigate to the required depth. There is a closed gate on the right. After the first level, you have to catch the jewel to open it. Pass through it to reach the next level.
Kliek op verskillende aktiewe elemente: enjin, roere en lugtenks. Navigeer só na die regte diepte. Daar is 'n sluit-hek aan die regterkant. Kry die juweel om dit oop te maak, en beweeg deur dit om die volgende vlak te bereik.
