It would be great if there was a progression guide when playing the game. This could be a book that is given in the starter house or when a player spawns in. This can also be something in the GUI as well.

That sounds like a great idea. I wrote this suggestion because things such as getting command block books can be hard to figure out for new players.

If you're looking for a progression guide, there's some modpacks with a guide book, one I'd recommend is A Withering World

well this could work in servers to help friends but i hope cracker doesn't make it too obvious what to do. more like a puzzle

Won't be adding an in game progression guide at this moment.
