Sorry, no update this week. I got distracted. I am, however, taking a close look at how I'm transitioning from teaching one concept to teaching another concept. As always, having the preceding level (containing mechanics the player is already used to) foreshadow the goal or form of the proceeding level (containing mechanics the player is no to) is like giving the player a stepladder to understanding. So I'm trying to make my transitions better through that.
