Sup, that sure is a lot of text, let me try to go point by point.
1.- I guess you're right, I was thinking more on the esthetic than in the functionality when placing the lab.
2.- I build Sayoko's team thinking on it as some sort of puzzle to solve on the first build, you have lillipup with bite on the same route, pikachu on the forest, and aron and sandile north from the city, and a level 9 or 10 fennekin should be able to brute force the battle, but yeah maybe is too hard, at this point I have no idea.
3.- I made the other trainers weaker thinking on two things, first that Sayoko does says that she's strong, so having everyone else having equal or stronger pokes would make no sense, and second, to be able to use them as training if Sayoko's fight is too hard for you at the moment; and fennekin does have higher base stats.
4.- If you are willing to take the time to feed all the berries to a level 5 bunneary to make it evolve at level 6, then who am I to stop you.
5.- I guess is more of a personal preference thing, but I feel like choosing your own name is like what everyone does, idk.
Now with the bugs.
6.- I didn't understand the Dawn thing.
7.- I didn't knew that, I'll fix it for the next update.
8.- I wasn't able to replicate that, do you still have the camera off-center?
9.- For the dialogue options, in general I wanted to make a "silent protagonist" so you can like fill it with yourself or something like that, but when interacting with the characters it feels really weird that you don't answer anything to them, most of the dialogue options are basically the same, but some have small joke answers, nothing big.
10.- Having a lot of options is ideal in my opinion, when we have over a 1000 pokes available, filling the routes with first route rodents is kinda lame.
And your questions.
11.- I guess that is more of a technicality; I understand sharing as having your partner having sex with someone else, in doujinshi and games is usually depicted more as a way to humiliate said partner than a cuckold thing; but in both cases, that's not my thing. Swinging is basically partner-swapping. Meanwhile what I'm going for is more of a harem route, where you have multiple partners while you act as some sort of nucleus of the relationship; it is a technicality? yes; Is it hypocritical? yes; but I will die on this hill.
12.- They will, my plan was to make an scene for braixen in 0.2, but I didn't had the time; now about the sentient level and talking capabilities. The franchise itself is really weird about it, in the games at the start it felt like the idea was for them to be like slightly more intelligent animals, with some legendaries and psychic types having a more human like level of intelligence, but as the generations went on, they got more and more human-like in their level of intelligence and behavior; and in the anime they always had a human level intelligence, but all the human characters treat them like pets; but yeah, I want them to be like smart furries, with like a human level intelligence but with a more animalistic attitude, behavior, or nature, not sure what the more accurate term would be; and outside of a couple of legendaies, no talking.
13.- I ran a poll on patreon to choose between a male and a futa mc, or both of them, with the detail that if the option of keeping both won, I wouldn't put so much emphasis on the gender or body of the protagonist in the scenes, not because I don't want to, but because of a time issue. And keeping both of them won, so yep... maybe in the future I'll make scenes with more focus on that, but for the moment that's not a priority.
