I am having this very same problem. Unfortunately I am unable to solve it as simply as Kafka did. I have completed all levels and all secret rooms, but cannot enter the dreamplane because this room will not stay white. I can solve it blindfolded and it still returns to red. I have tried moving on to the sixteenth level and then returning and there it shows up red again. This is so frustrating because I spent days solving 3N on the 22nd level and this EASY room is keeping me from getting to the dreamplane. I have received some excellent help to get to this point. I hope someone can help me with this toughie.
I note that I have only completed twelve rooms on this level. Is it possible that I may have missed a room?

I have a problem here. I have completed the room, and it turns green on my minimap. I leave, and get the "Exit Level" sign; but this room then turns red again. No matter what I do, it doesn't seem to recoord my victory. I'v completed the room several times, and I have my demo, which puts me in equal first place with dozens of others; but I can't progress. Is this a bug, or have I missed something?
