I didn't want to add tutorials or help until very late into the project (to avoid modifying them if something changes in the core) but recently I started to think about a tutorial, at least for early access. Introduction to various gameplay mechanics. In the final version I'd like to have a... hm... a companion that helps you out at various points when it seems that there are some problems. Of course I have an idea how to do that and of course I anticipate that it may not work properly, because it's dependant on guessing if the player has some issues with the game.
