To 1st:
Well, it's YOUR Game, so it would be nice to see what kind of story YOU have to tell, i.m.h.o. <3
And you should only take (kindly made) suggestions into consideration, that do not "betray" the essence of your Game - otherwise I don't think it can become its best-possible version because you will never be able to "please everyone". But you can be true to your own vision and inspiration - which will be valuable to look back on once you're older (as me ;-) ).
To 2nd:
Well, I don't know where the story will go and if this is part of what you envisioned, but I sure would love to be able to be physically intimate with the two godly "stud-muffins" somehow (one, the other or even both - Gods are just humanized archetypes, so they're bound to be quite "virile", as we can see in almost all the "Pantheons" of Gods created by Humans).
To 3rd:
Well, I think as a creator/destructor (much like the Trinity-of-Aspects of the Hindu God-Union of "Brahma-Vishnu-Shiva", who are all Aspects of the same Entity) he needs to be quite agile and perceptive to realize when which aspect is needed/important/applicable, so I think the "fitter" version does look logical in a way (since it's a "projection" of an archetype into a human form after all).
But there could be a state of him, that has a belly - when he's filled-up too quickly with semen by another god or his apprentice, that breeds him to proof his "mettle" and challenge his God-"daddy" to show off what he's learned and challenges his skills in the process, for example.
Yet, that's just a (naughty) possibility I imagined in the rough framework I perceived from the start of the Game so far. - I might be far from what you've intended, though, but that's at least what my imagination would wish for for an NSFW-Game like this.
And so far, I perceive Torent as one of the most beautiful characters, who has a calm and powerful attitude, yet also hides an evenly powerful virility underneath his loincloth, that he only shares with those who are "worthy" of his love - since it does seem that his greatest and most precious gift would have to be his "essence" (seed/-men) being a God an all...
I'm not really into Mpreg stuff, but I would imagine, some folks might like an optional route for that, too.
For me, just blasting his love-juice into his lover(s) and keeping this powerful essence sealed long enough inside of them until they've absorbed and grown more powerful, healthy - and more deeply and meaningfully connected/attached to him - sounds more than enough with such a character.
Just make sure, you don't get influenced by others too much, if it's too far from your own vision. Since I could still RP something like that on many platforms (Bonfire, Second Life, whatnot), but your story is yours to tell for a reason...
Cheers and hope my sharing of my naughty imagination - which is inspired by the start of your story so far - maybe inspires some unique path for you to implement. I'll be looking forward to be surprised what you're gonna do eventually. Just don't get stuck in too many options - that might probably paralyze your "flow" then (I know what I'm talking about there lol )...
