Thanks for the bug reports. They will all be fixed next patch. Regarding the NPC who increases Azar's route: I had added him for testing purposes. I suggest you don't use him, as you will miss her first mission, on floor 4. Also the story variable and the romance variable are different, so you don't actually get anything from using it other than skipping content.
- All classes can alter their stats as they wish, the only differences are the starting bonuses. (sword artist: +1testo -1estro, berserker: +2testo -2estro, assassin:-1testo +2estro) (yeah, the blood magus doesn't get bonus estro or testosterone, but he does start with +1 insanity). The decisions you make along the adventure slowly change your stats. Since it's a relatively new mechanic I'm still adding new events that help you change them
- It's not implemented yet. It's where Azar's third mission will start, once I do add it. For now I am making Kaliska's (sword artist) and Nao's (assassin) next mission for the next patch.
- Brain suckers are all over Psema, looking for people with unusual brainwaves. They are the pink monsters Cherry mentions in the inn, in Floor 7. Also, it's not only the brain suckers, there are crows as well flying above you, which normally do not appear, along with other changes. This basically means you've made a lot of choices that increase insanity. For now, insanity has the most major effects on floor 10, but it changes things a bit all over the place, and that includes the brain suckers.
- You might meet these Yuki Onnas again in the future, depending on what choice you made in the end of the dialogue. There is also another one, in floor 11, though she is a bit less pleasant than the ones in floor 4.
- Oh yeah, they will appear in future patches. The mythology I am using for them is a mixture of classical fairy tales with Stephen King's version, taking the best (read: worst) of both worlds. They are a criminally underused monster compared to other typical enemies, like minotaurs.
- Voodoo was only added 2 patches ago, so I'm afraid it only has 1 recipe for now. Eventually I will get around to it, but don't expect anything in the next patch.
- Well, like the Azar torture scene, it's there to increase your insanity :P You were given the option to walk away in both cases (PS: increasing insanity makes the game creepier, but from a gameplay perspective it's not strictly bad. It unlocks new items/merchants later on).
- Again, estrogen/testosterone is relatively new as a concept in the game, so their influence will only grow over new patches. For now, Bloodfang and Agmaur (floor 10, egomaniac dragon) are the ones who appreciate it most, though there are others too over the course of the adventure. Unlike testosterone, sex scenes with estrogen will sometimes decrease your stats a bit, going with the theme (though they will boost Bloodfang's much more). While I will add various events and fun times here and there, the main plan is that Theodoxa is where testosterone will shine, and Politeia (ancient athenian city) will be where estrogen will shine, in terms of what benefits you can get. It all depends on the NPCs who have power over each place.
Glad to see you're enjoying it, thanks for the reports!
