Jeez. I'm not sure I can even finish this game. Since, it looks like the teleporter system might be messed up in the castle.
I've tried following the instructions displayed on the stone tablet before you enter the teleporter section which would be 1, 3, 4, 3, 1, 4, 3, & 2.
I've also tried combining it with the segment found if you go on the path opposite of the entrance to the teleporter area which would make the total password be 1, 3, 4, 3, 1, 4, 3, 1, 3, 4, 3, 1, 4, 3, & 2.
Regardless of which code I use. I can't seem to get any further in the area. So, it makes me wonder if one of the doors in the area takes you to the wrong room. Or if the code given in the game is inaccurate.
