This looks like a fun mod. Any chance of adding Advancements and/or a manual that at least lead you into making the portal?

Just waiting for some one to do them.
https://github.com/skylinerw/guides/blob/master/java/advancements.md

Currently being worked on, expect it to be added in the nearest update.

Closing this issue since Advancements have been added, including the requested portal guide.

Some proper advancements would be a great thing to add. It's all done with resources now so it's easily implemented by the creative team. :P
