So its been a bit and I've only been able to play Lyall's route and have only got the first two endings. I've seen quite a few mess ups with their pronouns, so if you liked I could perhaps screenshot them and send them (I am unsure how to make a bug report, so unless you have some guide I could follow, this is probably the best I can do). I also noticed that when it came to Lyall, contractions weren't used very often, which caused the script to not flow as well, so please don't be afraid to use contractions for They/Them pronouns. And before I get into how I feel on the two endings I've gotten so far, I would recommend maybe setting up an option on here for the walkthrough to be bought, instead of just getting it through Patreon, but from what I understand, you don't feel comfortable with that. I don't completely understand why, but maybe offering something else along with it, like an artbook, could make it more comfortable?
~~~Vague spoilers ahead~~~
I have to admit I didn't expect Lyall to be as good as they are, since no one on your team is nonbinary. I mean, I know research was done, but without constant feedback from someone who is nb or someone who has had a similar experience, I am impressed. A piece of advice I could offer, should you decide not to consult a nonbinary person during your next project, is that a person is a person, no matter what labels they use or identify as.
Moving on from gender, I really love Lyall's character. I don't want to accidentally spoil anyone, so, as my warning states, I'm going to try to be vague. Lyall is relatable and honestly probably going to be my favorite character, even if I have yet to really explore the other two romance options. Just like. How they are loyal/attached to both Aliya and [spoiler] their pesudo parent. And how broken they get at the really big choice at the end are so real and human. And though I have yet to get the third ending and the hidden ending, I don't think much could change my mind on how much I like Lyall.
I also apologize, since I'm trying to be vague and its been a while since I played, my current review is lacking. I hope once I finish the game I will be able to give a better review/feedback.
