Makes sense! I like the new system, now that you explain it. It prevents the heroine from regaining all her energy while bound by letting her waste it on doomed attacks.
Good update! The main bug that occurs is that statuses like kneeling and restrained seemingly do not effect attack availability.
The voice acting was perfect in every aspect, he attracts a lot of sympathy without feeling pitiful.
The first thing I though when I saw the painting glowing after picking up the key was "Do you remember our venerable house?"
