Well, you could always make Winry a Marowak. Unless you consider the orphan part outside your morality, instead of just the age? Also, might I float the idea that evolution doesn’t have to be seen as adulthood - just like you could have a level 100 Cubone, just by keeping it from evolving, you could theoretically have an adult that just didn’t evolve (unless evolution is an inevitable part of ‘leveling up’ in years in your canon, and not something that could be suppressed - like a person growing up, but never really maturing as a person). It might even be an interesting world-building thing, having Pokemorphs without evolutions be the sort where they are the ‘old soul’ or naturally mature/stable/‘put-together’ type, while Pokemorphs that are from species that have evolutions start obviously immature, need to reach stages in social and logical growth and development, but maybe stand to be truly impressive people once they’ve fully self-realized. But, maybe that’s a bit too philosophical for a ‘let’s chase these Pokefats, because it gives me dopamine’ game…
Let me throw this out there: I don’t know many people, especially in this modern-day-epidemic world, who would doubt that life can come and kick you into the dirt. Life happens, and I feel like you shouldn’t need to feel like you have to apologize for that or explain it. Take care - pretty sure people can wait, and it’s not like it matters if they can’t (being impatient never made something happen better or faster, or even guaranteed it would happen; often the opposite). What you said about your mom sounds horrible, and I hope she’s going to be alright. I really hope that was hyperbole… If not, well…yikes on bikes, and I hope doctors can help her recover at least her health and mobility in some way.
Hang in there, and please don’t make a passion project into another stress on your pre-existing real life stresses.
