I'm mostly focusing on browser games right now because let's be honest, is your oshi going to download and run an .exe file some random person on twitter sent her? Probably not. So right off the bat I discarded any language other than javascript. The thing is, though, if I ever come to a point where I think I need more cpu juice I can switch from javascript to java (keep reading) with very little effort and make something faster.
As for the engine I'm using, it's not really an engine but it's called p5js. As I said it's not really an engine but it's kind of a framework for "creative coding", if you go to their website and see their demos you'll know what I mean. p5js is a javascript port of Processing, which is the same thing but in Java. So if I ever need more processing power I can port the p5js code to Processing code (I think) and it should run much faster using Java.

I made this rhythm mini-game inspired by a tweet this girl made in which she was making her character twerk to the beat of a song and it gave me the idea. Here she is reacting to it and playing it. Sorry it's in Spanish and I haven't gotten around to sub it but you can kind of guess what she's saying. https://files.catbox.moe/42kzoz.mp4

And then I had the idea to make a game inspired by one of those old flash games called Trial Bike. Remember those? This was a pain in the ass to make and I was never satisfied by it but whatever, I tweeted it to her and she said she wants to play it on stream. Also this game was kind of special because I got some help from anons in the general where we discuss these girls, since one helped me with the AI generated illustration and another one helped with the 8-bit music adaptation. That was pretty cool and it almost felt like a community project.
As for future ideas, one my gaming passions has always been platformer games and I'm hovering the idea of a game like EverybodyEdits (except no multiplayer).
