All right, i'm on Episode 3-3, up to the part with the Door and the 2 lamps outside it. You need to activate them both to open the door. I've got one lamp on but i can't find the switch for the other one. For this i need to get past the room south of this door. There's a Mirror in the Middle which you can hit to open the coloured doors. The problem is hitting the mirror, it's surrounded by the sand that makes you go in different directions. Please Help, i've been stuck here since the Japanese release.
