Are you asking specifically about single player or mud?

@Arkandias Okay I'll try to answer your questions, I actually had to give the latest version of the game a try myself since I haven't played for a while and the sleep mechanic is comparatively new, then I got lost in exploring some new stuff I hadn't seen before.

1: The command is rest. If you rest correctly you gain the ~"well rested feat" which gives you a plus two to all stats, which also equalises combat a little. I do admit the "your not drowsy" response for sleep or nap is confusing.

The reason it isn't working correctly is that either you have run into a bug, or more likely you don't have the cot with you.
If you don't have the "roughing it" feat or the  cot in your inventory resting won't restore anything. If you do have either the cot or "roughing" it" and your not seeing the "well rested feat" turn up after you rest (check the "look me" command), then its possible you have got a bug somewhere and should report it on the fs forum.

2: typing "nav" on its own brings up a list of locations, they're organised by district, EG "high rise, Zephyr" New locations you find or hear about will turn up on that list, or if you have the "city map" feat you'll see everything.

~Typing "nav" and the name of a location  will try to travel to that location (possibly running into trouble along the way). So, to get to Zephyr  type "nav zephyr" (be sure on spelling and typing everything since the game needs precise input). 

The scientist you heard mentioned can be found in Trevor labs, which should appear on your map after you hear about it, so just type "nav trevor"

About hunting and exploring.

When your at a nav point, (when you see "explore" and "nav" listed as exits like in the central room of the grey abby library), you can type explore to run into a random creature or event, or hunt and then "event/creature/location" to look specifically, though it takes a perception check.

Bare in mind though that unless your playing in hard mode, most higher level creatures  won't show up until your ready for them. If I remember rightly the Panthertaurs Larissa at Zephyr tells you to hunt are level 4, and don't show up until you hit level 1 or 2.

if you want a good start off quest, go to trevor labs and see Dr. Mat.

Also, note that as well as the huge over world with its events and creatures, there are also individual hunting areas  in most locations in the game too with their own set of monsters and events, for example if you go into the mall and go east from the foyer, you can go east into the public toilets  use "explore" to check out the sewers, you'll need to do this to find one of the monsters for Dr. Matt's quest.

The one mildly annoying part of the game is that currently there isn't a way to track what quests you have or get details about them, though I know a quest tracker is in the works.

if your stuck on what to do try The Flexible survival wiki found here though read with care since finding things out for yourself is always more fun.

Okay, to answer your rp questions.
If you start in Bunker mode you begin with a human form, however yes you've already been infected. Your libido will rise over time and you will find yourself getting mutated somewhere, this is all part of the game, since the idea is that each mutation carries a strain of the nanite virus which is trying to propergate itself and prove superior over other mutations hence the rather overthetop urges to, mmmm, breed.
If you really want to stay human in form, try playing in researcher mode, though mutating is all part of the game's atmosphere, indeed my character on the fs mud is someone who was ravaged by a next door neighbor, and has now done a deal with Zephyr to get nanite shifting powers so she/he can take on whatever form she/he wants from any creature she/he defeats, ditto with the change in gender.

This is just part of the game's ethos, and how much you give in to it is up to your playing style and personality. I personally  always see the goal here as basically trying to maintain some sort of equilibrium despite the crazy new way things are going as well as  making a safe haven for other survivors and generally helping out where I can, but you do have some less pleasant options on occasion, some of which you might find yourself giving in to if your libido is too high whether you want to or not (though you can take feats to change this if you wish).

for a good idea of the game's world and ethos, go and check out The SMithhaven Mall and talk to the people around there.

Hth.

As regards the navigation command, Larissa doesn't say the name of the lab, but if you use the nav command with no arguement before you talk to her it should just show:

high rise district: Grey abbey library, zephyr.

Then after you talk to her it should show:

High rise district: Grey abbey library, zephyr, trevor labs.

No need to explore till you find it, simply typing nav trevor should get you there, or, if for some reason its not updated on your map hunt trevor.
Also note that trevor labs is spealt t r e v  o r, (you need to pay attention to spelling in this game).

Btw, did you start in blind mmode by mistake at the beginning of the game? This might explain if your running into troubles with navigation since blind mode (which has nothing to do with accessibility), negates the hunt command and marking stuff on the map, so the only way to find things is explore at random, which pretty much makes some quests impossible, so its not recommended.

With resting I'm not sure what is wrong, unless maybe this is also something with blind mode. When I tried the game resting always worked.

Btw, you might want to read This page on the flexible survival wiki which is on basic game concepts and contains no spoilers but should tell you about mechanics etc.

As regards humanity, the humanity stat in the game is a synonym for sanity and refers to your state of mind rather than how you look. Even if you've got cat ears, a scaly body, four equine legs with hooves and hermaphrodite private parts of both genders, you can still be perfectly reasonable to those around you provided you keep your humanity/sanity stat high and that your rising libido doesn't interfere with things too much.

Hmmm, this is weird. What did you set your graphic options too? maybe the text is being covered up.

Also  what interpreter/screen reader combo are you using? 

I just today downloaded the direct msi installer. This installs the game with a preconfigured copy of windows git  works fine with the Nvda interactive fiction addon.

Indeed, if your using the basic game file and winglullks with the Winglulks NvdA addon you might want to switch since the general interactive fiction one is rather superior to the specific winglulks addon.

If you don't have the general interactive fiction addon for NvdA you can Download that here

I would not recommend trying to play online since the web interface can be rather clunky, indeed that might be part of the problem.

If your using Jaws or system access I'm afraid I'm not sure what to recommend exactly at this stage, though I've heard Filfre is a good Jfw interpreter and that will play glulks games.

Sorry your running into trouble. I'm not sure what is happening exactly, but hopefully we can get it fixed so you can try the game out.

Hmmm, this is very strange.

I tried running the game in winglulks and with the graphics, and its still showing up on the map.
The top line should say "primary rooms zephyr" and then after you talk to Larissa it should add "trevor labs" on there.

I've tried monkeying with graphics settings and hyperlinks settings and no change either way, I wonder if this is something to do with your general screen resolution or your winglulks text settings? Could you try installing the preconfigured wingit version from the website and see if that works?

The only problem you'll run into if you don't have the map active, is that sometimes you'll meet an npc and be told to go somewhere, but not given a precise name to type into the nav command and need to look on the map to get what you need to type.

You can check the wiki for quests etc of course, but its more fun discovering things on your own.

As for the mud, the mud and single player game are very different beasts. I've enjoyed both in my time, but other than an overview of the setting, the single player game isn't %100 necessary to play the mud, indeed the mud is set a little later on in time than the single player game I think, its also less rampantly, in your face adult a lot of the time too.

Hello again!
So I've unstalled winglulx and installed the recommanded full game config and... and it works. Don't ask me why, but verything's going as fine as possible. The rest command is no longer buggy, the nav command works as expected. So thank you!

One last question though : flexible society, is it worth playing or not? The wiki doesn't mention it so much, so I guess this is a little like flexible infection, a approximative concept, but if you think there are some important elements of background or some interresting gameplay behind this, I'll have a look of course.

Best regard,
Simon

Glad things are now working out, god knows why win glulks is giving you a problem, but there's nothing wrong  the game with its installer and NvdA will work with it just as well.

To answer your questions, there isn't a quest log at the moment but I have suggested it on the fs forum and hopefully its in the works. Unfortunately the problem at the second is you often need to check the wiki to find quest progress which is slightly irritating. , you are dead right on Doctor Matt's first quest  requiring two griffin milk from a Hermaphrodite blue griffin and two goo from a goo girl.
You can find goo girls by hunting in the mall, however bare in mind the hunt command will only work correctly when your in an appropriate hunting area, ie, an area from which you can encounter random monsters. The Mall is very big as a location with lots going on, but there's only one place inside it you can find random monsters, at the public toilets east of the food court, that is two north and one east from where you enter. You can explore the sewers by going down from here.
Once your there, hunt goo girl will do fine. Once you have two of each thing, go back to Doctor Matt and choose the option to help him with his research, if the right items are in your inventory you'll move on to the next part of the quest.

In terms of mutation there are five parts of your body that can mutate, head, legs, arms, torso, tale/rump and skin. Mutations will also switch  genitals and breasts to a given length and size as well, especially if your repeatedly infected by the same thing.

I've noticed in recent versions more parts of you tend to mutate at once so there is less chance of being a hybrid, and of course you can take the singular fun feat which makes you mutate completely to whatever form your torso takes.

Actually, as the game goes on and you get more feats and better combat items, plus as you get some companions and pets to journey with you you'll find your mutations being a wee bit more stabilised, and one part of the  is seeing how things end when you get different mutations, whether ending via submitting to them or when the military shows up (you can see them early with either the givein or end now commands). 

Also, if you want a good guide on getting into things check out This topic on the wiki which lists pets/npcs you can find who come to the bunker and video tapes. I think its a trifle out of date since there are a few newer ones missing such as Zoe, but it should be worth a read.

As regards othergames, wave  changes is more a concept demo, though it also serves as something of a prequal as it shows you lots of infections in the city.
Flexible society I actually rather like, but sadly  development stopped on it because the idea of forming societies among clans of different mutants wasn't as popular, and a lot  the direction of development for the games  comes from the patrion.

Flexible society sadly is a bit hard to progress in at the second, since to raise a lot of skills you need research points, and there isn't really an efficient way to obtain them in the demo as is.

As regards the mud, yes, you can treat as something of a later encarnation of the single player game, albeit one with very different mechanics and multiplayer capabilities, though I'd also suggest thinking about your character and background as well as how you want to play the game.

Hth.

Where do I get the General Interpreter addon? Last I tried it, it did not work with the regular Winglulx. I want to get back into this and other games.

Hello!
I'm curious. I know this game has an important experimental side, and this could be the reason why I'm experiencing this issue, but ...
I've tried to save my current game a few days ago. I had allready done this before and it worked fine. But today, I tried to restore the game from my save file and... it partially worked as far as I understand.
First, let's say that I'm sure that I have lost things, like done quests, some credits and levels, etcetera. Everything seems to be directly drawn from my first save, which is, of course, not what I was looking for.
I'm almost sure that, when I saved my game for the second time, I correctly replaced the old file with the new one. Is it a known bug, or does it sound more probable to you that I just did something wrong while saving ?

Best regard,
Simon

Hm... Strange.
When I launch the game, I'm immediatly told to configure a new one, so I let all the options by default to go to the next step as fast as possible, then I use the restore command. Maybe I shouldn't have kept the name of my original save file, otherwise I cold try to delete my save feel as soon as I load it to create a new one each time I save. This could prevent this from happening again, but allow me to progress between the two saves...
It's still possible that I just pressed the wrong button and didn't replace the file, but it'd be surprising.

Best regard,
Simon
