This game is way too good to be so short. The one puzzle it has is excellent and then - it ends. It's like watching 5 minutes of Indiana Jones or getting a plate of delicious dessert with one spoonful left. The author twists the knife by making the game deliberately look like the last puzzle of a grand adventure.
I like to think that during the last 8 years after the publication of SMatJEoW (yikes!) the author has been expanding it to a full-blown game and just waits for the right moment to publish it. One has to have dreams, right...?
