Something you may not know: The way Itch works, all comments get slopped together in one feed. If you have multiple games published on an account, this means you may not realize what game is being commented on until you glance up at the header. I was really hyped as I started to read your comment...and then I realized it wasn't even on GT, just the first game. If you like the FIRST game this much...I'm definitely looking forward to your thoughts on the second. This first game is just the breadsticks, GT is a...pretty sizable meal.
More seriously though, thanks for taking the time to write out your thoughts in more detail. I am somewhat unusual, in that I genuinely need a bit of backstory to enjoy my porn. Even with generic pics I find, I end up putting together a whole setting for them. Just the way my brain works for better and for worse. But when making a game like this, it means I actually try to give it some meat, some kind of identity besides the bare minimum. And hopefully it's a "works on multiple levels" thing: those that just want some sex scenes, there they are. People that want a little characterization and setting, that's there too. People that want DEEP LORE: let me put it this way, there's a computer in GT that's nothing but lore dump. Optional, but the details are there for those who care.
As for the characters being basic, keep in mind this was basically a proof of concept. But they are filled out MUCH more in GT. In terms of the combat, I will never claim I have super complex amazing systems or anything. But there's a number of things to say there:
One, please understand, this was my first ever time working with RPGMaker. I learned as I went, but there are a lot of rough edges, and I was mostly just trying to make sure the combat wasn't AWFUL. Second, I'm somewhat constrained because every new enemy is a new art asset I have to create, AND a new battlesex mechanic I have to consider, and possibly MORE art assets because of that etc. You'll see more of what I'm talking about in GT. So as a result, I mostly stick to one enemy type per game, with some variations for gameplay, differentiated by pallet swaps. The variations were extremely basic in the first game, there's a LITTLE more there in GT, but not a ton. Also TECHNICALLY there are two fully different mob enemies in GT in addition to variations, but you don't really FIGHT one of them. You'll see when you play it.
Third, as I just said, the battles in my games aren't just about normal mechanics, they also have to have a battlesex layer on top of that, which adds to complexity. And you start increasing that complexity in a...non-linear? way as you add things.
But fourth, I don't really prioritize super amazing combat highly anyway. I want it to be somewhat fun, and at the very least not get in the way, but the core thing in the games is to be HOT. Not just to have hot things in them but to BE hot, to manage the experience so players are getting dragged along juuuust right. I don't mean to rag on Grove, but in contrast their combat is SUPER intricate and sophisticated, or at least it was when I tried it a year or two ago...and it kind of put me off the game. I don't want to make my games DUMB per say, but I'm always careful to never make people think TOO hard. It gets in the way of the flow.
All that said though, combat DID improve at least a little in GT; I'd be interested in hearing how much that improvement helped for you once you've finished it.
As for translations, by all means. Just know it's quite a lot to translate. But essentially the rule is anyone can make one, just be clear it's unofficial. Then I'll try to take a look, make sure it's at least fairly solid and complete, and make it semi-official with a notification/news post here. And eventually, hopefully, actually fully test it and make it FULLY official. That can take a while though: the chinese translation has been languishing a while because I don't have time for full testing atm. But long story short, you want to give it a try, knock yourself out! It's always fun seeing how people handle slang and jokes.
