It took me a while to figure out that the crown sprite was evolving with turns. More feedback would have helped me understand better when to run away from monster. Also, does possession only consist in the loss of control of the character? I can't get the amulet in the last room either, should I defeat the green skeleton?
Anyway, even if the gameplay would need some polishing, the presentation is superbly done (sound and art) bravo! A good performance in the given time.
