I’m not a chess player, but I’m aware of the Knight’s tour, so I appreciate the lesson, but I found it hard to relate the framing narrative to the actual gameplay. You are meant to me a messenger going … somewhere?
I guess the intention is that you have to visit every square, because each square is a colour coded village, but the talk of forests, and sentries, and repeated patterns made it harder for me to understand instead of easier, I think. And there was some cognitive dissonance when I saw the board and it didn’t have forests or roads or indeed villages on it. All the more so because there is a town/house on it, but that doesn’t actually mean anything in the fiction (even though it does to the puzzle).
One other thought. If the idea is to actually test the player’s understanding, maybe suppress the “action” cursor on the correct choice, because as it is you can just wave the mouse around and see which one to click.
