How about a red, blue, green, purple combination in the first room? Here you have to push statues over the matching tiles. and when all four are in place the door opens and you enter room two.
Here you can have 4 switches that the hero must activate, and they have a time limit before they deactivates. All four must be activated before room 3 opens.
A little mace, that changes a bit, depending on wich switch you have chosen to activate before entering the maze. 4 switches, and only one opens the way out.
How about it?
Think you can do it?
