@Infirnex - Before you start, don't forget to read the stickes and the info threads linked from the dev. chain

Other than that, good luck with your slot

*EDIT*
Just tried your work so far, pretty nice stuff, pretty interesting but for some reasons it didn't make the chaos a lot better. I still get lost, it's a good thing to have this huge nonlinearity but the problem for me is still - while playing I have no idea where to go next.
We have now locations for all three different colored doors, we have placed the keys, it's time now to get some more linearity in the phases between, where the player actually knows "this where I have to go" and not to think "damn, where is the door for the red key?" or "damn, what has been opened by this switch now?"
Beyond, your area is very (!) huge... would be a good thing if the upcoming mappers wouldn't add these kind of scales (was never meant to be more than one room/area anyway), otherwise the map will be huge and nothing can be done about making it playable anymore.
