please add a guide on how to get and setup transport rings

Once they are in a state where such a guide would actually be useful, then I will do that. Right now they're just terrible.

Maybe not improve their appearance, but add sound to them, and fix addresses using memory crystals?
And add craft?

I do not know how you came to the conclusion that I only want to "improve their appearance" but no, when I say they're "terrible" I mean that every single thing about them is bad and needs re-doing. That includes appearance, sounds, how they're used and so on.

Crafting will only be added when I feel like they are in a good enough state to be crafted.
