I have just come up with a very good idea today for Rabbit Adventure. I'm going to make Spaz have different levels from Jazz by making an intro level, and making Jazz and Spaz have different Start Postions and making them have different exits too. Here is my level list for Spaz:

Levels 1-4
*The Darkness Marsh
*Deforestation
*Sandy Paradise
*Dunes of Disaster

Levels 5-8
*Holy Temple
*Aztec Mountains
*Island of Beauty
*Pirate's Raid

Levels 9-12
*Sky Fortress
*Aerial Battle
*Dino World
*Prehistoric Nightmare

Levels 13-16
*Sacred Islands
*Statues of Worship
*The Forgotten Labratory
*Sacred Stones

Levels 17-20
*Hare's Clouds
*Decent.....
*Pits of Hell
*The Final Showdown

Because of this, RA Levels 1-4 definitely won't be on J2o untill next year.
