That sounds great. I like the idea of the ever-shifting castle layout and having the enjoyment of exploration every time. But perhaps monsters and bosses slain you would not encounter again (their rooms empty now), on backtracking you'd get a bonus of one room less to count for distance to roll against (as you feel a bit more familiar with the castle on subsequent runs), having tried to escape before could be one memory you already start with now. I believe there should be a ton of interesting things to introduce in an iterative play scenario. Thanks again for the elegant, inspiring game.
