Okay, let's do this! we need to think of more mechanics to introduce in each world. At the moment wink is an actor that follows you and titan will be a wall the player can push. here are the worlds:
1 - Grassy
2 - desert
3 - beach
4 - sky
5 - snow
6 - lava
7 - void
The player will see a cutscene between all the worlds...
also about the 'void' world, at the end of lava world you fight the sorcerer and the atom-slicer explodes, creating a giant wormhole in the lava land. Wink and Titan have to find all the peices of the atom slicer and put it back together so that they can get home.
