Marbelara is the first level of the episode The Chase Is On from Jazz Jackrabbit.
This is the secret playground of Devan's elite SchwarzenGuards, a perfect place for them to play phaser-tag! Just make sure that you're not "it!"
Marbelara presents a big difficulty spike compared to the previous stages, as you'll have to deal with the tough Schwarzenguards patrolling the areas, Firebombs jumping from the lava pits and the trees which will also shoot at Jazz, as well as the Drageens on higher difficulties. The path is pretty much linear on both areas of the stage.
At the end of the first area you can find a secret passage to the right of the goal sign which will take you to a bonus area with plenty of items to collect.
