Hello! Thank you for enjoying my game :)
Releasing on Steam in the future is something I would like to do but I do not have any direct plans for, as I am dedicating all of my free time to developing 'Favor' currently.
____________
Regarding the choice you mentioned below, here is my logic:
"What about him?" - is a direct question, indicating curiosity, interest, and willingness to learn what is likely a 'bad side' of Binary star.
"...really?" indicates a pause before the question, with my intention being that the player is either doubting what is being said, not wanting to believe it, or possibly just dismayed towards what is being said.
To me, this pause indicates the player character having more attachment to Ray rather than the former "What about him?" which is seeking out specifics without any pause or doubt.
I understand this was a little vague and my intentions may not have shown through, but I don't personally always like to make choices straightforward. To me, I feel that the best choice-based vns force the player to take into consideration their situation, the LI's personality, and the tone of what is being said.
Granted, I am not a pro at this as a dev yet, but I would like to continue to improve :)
