Son of a bitch I forgot to save.
Again. The first two bridges room was a pain in the ass to build, so I'm just gonna redo the room before it and use Teledoors to connect the branching paths.
I also did two other rooms:
The trapdoor doesn't open. I can't bothered to make it work without tearing apart much of the ground beneath it.
This room isn't finished. More detail will come later when I connect the branching paths. I'm mostly doing these rooms by memory, so I don't actually see what they looked like in the original game until I've finished them.
Don't ask me how I'm gonna make the pool freeze. I probably won't. You only get a key in the original game anyway, and none of the castle doors in this build are locked.
