You can see a different enging to the game if you can complete it with more than 70 Red Gems.
At the title screen go to options, then enter the following sequence using the second controller:
L, R, Start, Select, X, Y, A, B.
If you have done it right a sound will confirm the cheat has been activated. And you'll be able to select which level you want to play when you go back to the title screen. Hold L + R and press Up or Down to select the level, and Left or Right to select the section.
When you are playing the bonus levels, try pressing the B button when the genie blinks and you'll get an extra life.
