It's hard to say how you'd go about making it super explicit without making it lose some charm... and you can't go all expo-mode with walls of lore up front, so I suppose it was ok as is .. but maybe some of the questions left me wondering if I did the "right" thing or not (like imprisoning the sister.)
Also congrats on your reasonable playthrough (once) time! I fear ours is like wayyyy too long for folks and they will not see the endings. T-T
