Aseratrix
- Lilith's Throne
- rich / yes [maledom, lezdom]
- medium / with specific characters [to my knowledge mostly with the maid at a demon(?) guy's mansion (you visit the mansion as part of the main quest and can start a femdom relationship with the maid there; plus you may be attacked by other creatures/people throughout the game)
- narrow (I think, I haven't been playing it a lot) / pet play, public humiliation, shoe worship, verbal humiliation (possibly more)
- hetero/futa/gay/lesbian / male or female [character created by the player, content mostly depending on player choices; player can transform into fantasy creatures and change gender]
- choice and battle based text game with some sprites
- Java / in dev / Innoxia
I was dreading to add this game to the list (for the difficulties of classification it would bring), but it certainly qualifies.
If I may add to your post:
Lilith's Throne is a curious case. The game is all about transformation of the mind, species (furries everywhere), sex(vag, vag+penis, cloaka and everything in between) and form (slimy, udders as breasts, wings...). You have the option to give and take fetishes, add tails and antannae and sexual organs of every generic NPC after you capture them or even mid combat. There's a generic sex system in place that allows for a plethora of options.
Fetishes range from domming, incest (with your own children), all the classical acts and weirder ones and so on and so forth.
All sorts of sexual acts and preferences can be combined with a plethora of sexual stances and positions which pretty much covers the vast majority of conceivable acts; but without any meat / story behind them.
Facesitting, enforced addiction, cbt, non-con, licking, feet worship, pet play... you get the idea.
You can be on both sides of the coin since you can alter yourself in the same way (and can be altered forcefully if you allow it in the options).
Did I mention Lilith's Throne has a slavery system with milking tables, so technically classical slave / master and milking are also a thing?
Concerning actual, meaty femdom content:
There is the aforementioned Succubus-Maid that gives you foot worship and petplay scenes; which is also the most fleshed out from every other noteworthy interaction I'm going to mention.
Prowling enforcers do cavity searches and can use you to pleasure them; genders are random.
In the gym you have a dog-morph that forces you to train, sweat and take it after the workout sessions without letting you cum. So, a workout pegging fetish with denial?
Down in the warren there is a rat character that makes you addicted to her cunt-juices and enforces monetary compensation for the permission to get your fix by licking her during a facesitting; so addiction / Financial Domming, Facesitting?
With the last update there's also been the introduction of a shopkeeper in the new town that uses you as a live mannequin for her bondage products makes you please her afterwards by any hole or mouth available; not sure what to classify this as? Enforced humilation + worship / pegging / oral service?
If you want to count non-con as a sort of femdom (i doubt rape should count), there's also a character that forces herself onto you.
There's probably a few scenes more, but less femdom-y but rather usual cuntiness from bratty princesses and ordering you around.
