Nice devlog. A few thoughts.
Please reconsider the names. Sera is a female name and Desi, well, google it. If you insist, better maybe make it nicknames, like for Désirée and Seraph.
The game is whatever you want it to be. The engine is only a tool to make it easier to program. That said, if you do not want a kinetic novel, mini games and sandbox are good to break away from that. Illusion of choice vn with different ending in name only, are still kinetic, as far as I am concerend. As for vn, you know best if you want to have game play or just a branching story to read. Both have their fans.
Please be aware that this is a hobby. You can dream of becoming so successful that you can live from your hobby, of course, but indie dev is actually a synonym for unemployed (or overconfident boastful amateur with delusions about own skill and own game quality). You should still aim for a day job.
You can see the page view for topics and compare to other devlogs. Many of your views will stem from the same people though. And this section of the community is kinda deprecated as explained in the sticky.
I do not know how translator friendly rpg maker is. But if you hardcode the game in non-english, well, .... And if you do write wihtout translator in comments your engrish is good enough to write the game in that. But this is the opinion of a non native english speaker here ;-)
The problem with getting exposure is that you get exposure. People will say nice things, people will say not so nice things. Some only for the lulz. It is hard to see the valid criticism behind the insults. Your art so far sucks. That was not nice of me to say, but it is true. For me it looks not like pixel art, but like pixels drawn by a kid. If this is intentional, well, ok, can be done, but is hard to pull off. Art is a skill and takes lots of practise to look good. And without classes in that, it might take even longer. Also, even if you had a refined art style, people might just not like it, as it is a matter of personal taste. I do not like most pixel art in general for example. I think your chibis are good.
Oh, and your approach looks already more professional than most of the so called indie devs here. I wish you luck and fun with your hobby.
