Thanks for the feedback! I agree an in-game tutorial would be good. It'd allow people to learn faster than the guide I have up now on the wiki (and also I think not having the guide be in-game limits the audience too much).
I'm half delaying the in-game tutorial because: (A) I think there's a little more UI refinement I can do, which would necessarily make the tutorial outdated if added now, and (B) I want to add some more relatively-core-features like nobility, which could similarly outdate some of the tutorial.
Nobility I think will give the game a little more depth early on as these will be people that can help you along, but also sabotage you if you don't keep their interests somewhat in mind.
Anyway, if you think of more, now or in the future, let me know
