I still have a feedback about the linearity of the story if that's ok ! (I'm not used to writing in english so I hope it's understandable ahah)
I like that we can choose between pro-fae or totally loyal to the kingdom, but I feel we can't really choose how MC feel about being a changeling sometimes.
For example when learning about the shapeshifting ability, MC seems always reluctant or even disgusted by this power. I imagined a more pragmatic MC who had time to accept their changeling status would see this as an interesting advantage to use for their goal (to help the fae or kingdom), or a scared MC could see this as a reassurance and a possible escape if their fae-nature is revealed. A more open-minded MC interested in magic and fae magic could be intrigued, etc...
It was just an instance that I remembered and I forgot some, but most of the time the MC reaction was aligned with what I would have chosen 馃榿
