I'm looking for feedback on what you'd like to see out of the game in terms of potential NSFW content. I'm of mind to err to purely anatomical, scientific descriptions, though I know many will want some more detailed...things, but I also understand there are those that prefer to keep it at least plausibly deniable.
Currently I'm aiming for middle-of-the-road, but I could be swayed either way. However, please keep any comments nested here on the side of tasteful and not explicit.
I don't pretend to know about what kind of people play this sort of game, but as I see it, you play the game for the gameplay, obviously, but also for the NSFW content. If there are people who are offended by the NSFW or something like that, they'd probably not be playing the game anyway. Although I see where your coming from though. I think that leaning more toward the NSFW end would be better (and generally what I'd prefer personally) but have some sort of option for making it less explicit. I don't know exactly what you have in mind, but for example: the transformation dialogues in the observation chambers. Each one could have a shorter, more clinical description, and a more detailed NSFW description that could be toggled between via an option in a settings menu or just an option you pick before starting a game.
I don't know if you're thinking about adding visuals at any point, and if not, I see why. Having the focus be mostly on the text adds a lot more room for the imagination to give you a bit of wiggle room. Plus, there are a lot of really good games that are mostly or entirely text-based, so they are by no means necessary. Personally, I would love to see visuals, but I understand that it could be really difficult. I don't know if you're an artist, but even if you are, the amount of variations could be problematic (although you do have a pretty convenient framework for modularity built with each transformation being assigned to a body part). I agree with another commenter that silhouettes would be better, for the "imagination" point, and also the fact that it'd be easier to do a modular art system of body parts.
I think that middle-of-the-road is... not the best choice, since you'll be losing out on both sides from people who want a game that is more lewd, and from those who want something more tame. Plus, it makes your game stand out less. I'm not saying you have to go super hard into either end, just that it'd be best to stick to a side and keep in mind that they are your majority when making design decisions, even if only by a bit.
Anyway, TL;DR, I'd personally want to go the more NSFW route, but I think an toggle or setting of some sort is the best way of doing things. Although, keep in mind, that one side is always going to be your "default", as it were, so design for them first. (although take all my advice with a grain of salt. I have never designed a nsfw game in my life, and only ever designed a game of any sort on technicality.)
Different clients and transformations. Example is where either someone brings an animal or a subject that has a missing limb and you have to transform someone into said missing limb for them, and it could be something else than a missing limb. Could be an organ, a bodypart, ect. It could help boost the health of an animal to then sell to the public for more money for your experiments!
Honestly I'd love to see what is already present developed more. But when it comes to NSFW stuff then Maybe an internal log for what the workers are doing? You have (presumably) a base in game that you are managing. right now all the employees are just names on a list. It would be cool to have a "Security Log" That describes day to day interactions between employees. "Matt and Stacy went to the janitor closet. sounds of thumping and moaning were heard afterwards" those events could be further modified if the employees in questions have certain mutations. "Bull Anthony locked himself in the bathroom for 30 minutes. when he left few bottles of 'milk' were left behind." etc.
