I found this game around a week ago and i really like it. However i'm not sure if i'm missing something, but I feel like both meet and sex are really bare for what is a text based game. I mean most actions that just have a text of "it happends".  Tie her with a rope > "she has it", blindfold > "it's on", and they don't interact with overall sex at all. i mean just adding a line of text for when a slave has something on, it doesn't need to react to what you with some complicated interaction map, but when a slave has some device on just add a line of text for next interactions.

You order slave to grovel " congratz she does", and only one line of text for this. I'm not even gonna touch the issue that centaur can do lap sitting, and other race related Issues, that would be a pain to code i guess, but it would be nice if all non humanoid races had at least one unique action for their race.

there is no personality progression, if you just treat your slave nice and get her to her intimacy,  she still gets desires to have multiple partners or to be fucked in the ass even as a virgin.

And animals speak like normal people....

And same issues in the meet mode. Invite other slaves only makes one bonus, very basic bare bones line of text appear, that's it. And why is there nothing to do int the streets? Literally nothing changes while a girl is technically in public streets, that was such a good opportunity to make entire discipline section like for the dungeon. But no it's just another number multiplier(i assume?). Same story with rules for advanced brand, like pet behavior.

I like this game but it's criminal how many good ideas were thrown into it with absolutely 0 interactions just to be number multipliers, i am not usually one to scream about "losing immersion" but at this point, where half the buttons i press only change some numbers in the code i can't see it's just discouraging. And all it would take is adding a few lines of text here and there just to acknowlage your choices, you don't exactly need a team of writers for it.

Or am i missing something? Cause i didn't see anyone else here talking about it, and i feel like these are issues most people would catch on.

I'd say that your evaluation of the interaction systems is spot on. If you open the script files (.gd files are plain text script files), you'll find that in some areas there is the potential for a bit more complexity than the player is made aware of (lube exists in sex) and in other areas there is a complete lack of functionality where the player would expect there to be something (tools like the blindfold). Both systems use almost completely generic characters, even for the talking animals, so everyone has basically the same personality and reactions. Most of the variation comes from RNG or poorly balanced and indicated stat differences. 

You are not alone in wanting more from the interactions as they are quite monotonous, but adding significant variety quickly adds up to be considerable investments of time and creativity. This game ceased official development a couple years ago and only receives bugfixes(https://itch.io/t/1167355/bugfix-for-10d-v6b) when I find the time and energy. I don't mind including quality of life improvements from the rest of the community when I feel that they are appropriate, but my goal is to not significantly change the experience.

I suspect that most players simply stumble their way through the interactions as I haven't seen any detailed guides or chat. I opened up the scripts and compiled a chart of many of the actions for personal use (rarely shared on the Discord), though that is a bit outdated now. There are currently or have been a few mods that alter the interaction systems, though these are generally minor changes to include new actions. There was one mod that planned to tailor the meet interaction actions to the various traits, but I believe that was never finished. I have not seen any significant efforts to change the action transparency, though this is a issue with the game in general.
