Hello! This is me giving you a critique of Healer Games, as per our exchange! I'm sorry I couldn't do that on AO3, because I did put myself on the waitlist but my account is due for registration on the 26th, which would exceed the deadline.
So, commentary! The most noticeable thing of your story is... well, the story. I mean it. The plot is very enticing, it combines elements of the classic nuzlocke with dystopian fiction and blends both very well. I like how you focus on Morgan's feelings over the madness there is in this universe. It really gets to her when her Pokémon die - at least most of the time... in a way that's completely different from Sera's. Sera is like "oh, crap, I'm sad, but it happens".
Character dynamics are great. You managed to shove in two completely antithetic main characters and make their bonding and arguments interesting. I wasn't expecting them to grow apart so fast after they discovered their feelings for each other. It leaves a feeling of suspense to their relationship (interpersonal relationship, I mean, not relationship-relationship) that keeps the readers on edge about where they're going to go, what they're going to do - not just with each other, with everything else too, since they kind of are the heroes and man, there are so many ways their respective "allegiances" with the evil teams could go wrong.
Did I mention I like villains with a garish morality? And villains who seem to be in it for the shits and giggles? So yes. I like your villains too.
One thing I find worth mentioning is that there are far too many queer characters. And look, I'm anything but cishet. It's not that I don't like queerness. It's just overloaded, to a point where after chapter 20 or so, literally every single chapter outs some character as something. It feels forced and there isn't enough room to actually explain those identities, but even if there were, there'd be too many to count. You don't want to run a work of fiction into a LGBT+ manual. If you are to do visibility in your work - a noble purpose, for sure - then select a few identities and put those in. Don't just throw everything into one piece of work. Morgan is tastefully done, to the point where the conversation with Genevieve felt unnecessary (because her identity had been already abundantly explained by the many moments in which she'd expressed, or thought, about her being or not being "a girl"), and Sera is a playful representation of polyamory... Steven kind of fits as trans, but everyone else, just, please no. There's too much of everything.
Anyway, aside from that one qualm about queer identities, it's a good story and it has me hyped for more.
Sorry this critique is not as in-depth as yours, if you think I've missed anything or want a more in-depth commentary on specific aspects let me know! \o/
