Oh everything is fine bothways actually. Just keep the game going and I'll like it wherever you take it. At least for me, I don't necessarily need anything other than what the game already has, it's great really.

In my opinion, gender customizable ROs provide variety for people who want a certain character to be a certain gender, while predetermined genders perhaps make it easier to highlight some aspects of the characters' personality, which makes them more...idk, specific? Both has advantages, although I like the second one slightly more.

As for poly routes, I know some people like them very much but I aren't really interested personally. So I'm good whether you have one or not (I probably won't play it XD). 

I would really like poly routes! They give you a different insight in how the character is, and the dynamics are also interesting. Also, customizable ROs would be great, but as a commenter previously said, sometimes it's better to have a canon gender for stability. You could give the option to customize them, but also establish canon genders, it would be easier for content creators.

Oh i would really like poly routes! I love those routes because i tend to be the type that'll like more than one person, so having a poly route would not only be good for me, but will also give insight into the characters romantic relations with one another. I do like the idea of customizable RO's, because some of us will have certain preferences as what a certain characters gender should be lik

I avoid creator tumblrs (and related posting) because I like to go into games blind; also, sad to say, many games make it to the "Here's all the info, look forward to it! <3" stage before they run out of steam. As such, take whatever I say next with a grain of salt, since I've been avoiding even the tiniest spoilers! (So, no opinion on the names thing.)

* I'm good with canon genders, especially as someone who (sometimes, sort of) writes; sometimes characters spring into your head a certain way or evolve into a specific state, and it becomes hard to think of them otherwise. While I appreciate the option to choose RO genders, it's not necessary for me to appreciate and/or romance the characters.

* I'm not personally interested in poly relationships, though I know that some people prefer them or would like them to be available. It wouldn't turn me off unless it restricted characters to poly-only relationships, ex. I can't romance Character A unless I also romance Character B. It wouldn't be enough to make me swear off the game, but I might be a little disappointed if I wanted to start a (non-poly) relationship with a potential RO and couldn't.

I don't know much coding, so I can't give much of an opinion on the coding-based questions. From following the development of other games, though, it seems like trying to be too ambitious can be a one-way ticket to burnout, so don't feel like you have to meet all the expectations, especially not all at once. As a (future) player, I feel secure in saying that we're all supporting you, even if all we can do is exercise some patience!
