Sonic CD Blast using dark world

[flash]

Ok so I heard about this dark world thing and I was wondering how it works from what I get its like when a certain event happens the level changes into a show version of itself. So I was thinking could this be used to make a sonic CD style game like you run through a checkpoint and you goto the future/past?

Uhh, I think Flame the hedgehog has one of his big srb2 projects involving the normal levels going into the dark version, although it is not completed.

For checkpoints, unless you can do extreme Soccing skills, I highly doubt it would work.

The dark world is a part of JTE unused so far.
