I am building a fairly large single level map which has eight separate rooms.
In order to exit the main hall, which the player gets locked into once they enter, they must complete the challenge in each room. Once all eight rooms are completed the exit door unlocks.
There may or may not be a final end challenge at the end.
The challenges get progressively more difficult (at least I hope) and interesting mechanics are introduced in each room which eventually are used in combination.
The feel of the map is quite dark. I may actually need to lighten it up a bit more if there are any complaints.
Currently I am only finished with the main hall and room number 1. Room number 2 is 50% completed.
Screenshots:

Main hall at entrance.

Rooms 1, 3, 5, & 7. The number above each door lights up when the room is completed.

A view into the exit area from the main hall. The large panels on the wall light up as rooms are completed.

A view into room 1 from its hallway.

Inside room 1. Behind the player is a "keyhole" which the cube must be placed into for the door to open.
Comments/Crits?
