Yes, that tutorial mode extension is generic. It has a set of default lessons and tries to plug them into the contents of whatever game it’s added to, so often the results are also generic, or unsatisfying. It just can’t know any better because it doesn’t understand your particular game. Making a good tutorial that works for your game can be quite a challenge! (e.g. see forum topics like Writing a Tutorial Mode in Inform 7) It’s often best done once you have a complete game, or lots of game. I wouldn’t worry about it early.
Sorry if I’ve caused you any confusion with my nitpicking on Epistemology, and seen and unseen, etc. If you start to get your knowledge system going – whether it’s Epistemology, or a modified version, or something new – and find you need any help with it, let me/us/them know.
