I played the game but gave up after a short time ... (see my yt chain).
The main flaws: Totally illogical plan. Impossible to make a plan of the castle to find one's way there, whereas we should fall back on a place already seen, we end up in the end elsewhere ... In short, we need a real plan.
The torch that goes out by itself, that we relight with the lighter and that goes out again immediately causing us to lose since the energy decreases immediately (but I read that you corrected that).
Apart from these main flaws, I really liked the game which really makes you want to play it seriously once it is finished.
