i have a problem i downloaded the file but when i try to run hypnosis.exe nothing happens im on windows

Could be windows defender or an antivirus being overprotective, maybe? Sometimes it doesn't like to load from "unknown developers". But if you don't see anything like that, it might need to be downloaded again

its the second time i downloaded it but the same thing i even puted it in the exclusions in the window defender so that shouldnt be a problem when i try to run it it just do a loading curser for a sec and than nothing

That's odd, I've never heard of that happening before. Apologies, that's all the suggestions I have.

Is there any way to add the latest episode 14 part two in the already existing app? because otherwise surely I dont have to delete the whole game, lose all of my saves, download it again and play the whole game again just to view the part 2? Im really excited to view it, but im not able to add it into the current existing game, does anyone know how to add the episode 14 part two in the existing game?

any replies?:(

Are you playing on Android? If so, I don't believe there's a way to add or patch anything into existing the APK file for previous releases. However, it's possible to copy your existing saves into a different folder and then back into the new version of the game.

Yes I am playing on my pc so andriod isnt an issue, and thank you for replying, so how do I copy the existing saves and back into the new version?

Saves should carry over automatically with PC. It saves in a hidden file in your windows username folder, so Users/username/AppData/roaming/Renpy/Hypnosis

ah, thank you do much, really helped a lot, and also one more thing, how do I reach the Tiffany date in the end of episode 13 part 1? im following all the steps that it says in the walkthrough as well, and made changes in episdoe 12 as well, yet her ending in ep13 part 1 isnt appearing, am I doing something wrong?

In Episode 12 you can't be dating Hottie Bartender, otherwise you're busy on the phone with her when Tiffany walks by in the hallway of the apartment, and you don't get the chance to say hello.

i'm going to sound stupid but what's the difference between hypnosis application and hypnosis -32

32 is for older machines, most run the regular version just fine.

thanks

(1 edit)

Am I tripping or is a there a path where you go shopping with leah? if so can anyone tell me how to get it?

Yep, that's the start of the new content for this update for v1.4.6

Hi im at the pool party ark but i have a question will any of the side Ladys be part of the harem ending like Britney for an example or will it be only the 5 main ladys?

Each of the girls the main 5 introduce to the Main Character will be (optionally) included for harem endings.

thank you for the quick reply, i look forward to the end of game coz there all gonna be added mwhaha lol

Is this game linear? It looks really good but im not a fan of linear vns

The story is told sequentially without skipping forward or backwards much (there are a couple of flashbacks, but are not a big part of the story), but there are several different paths, including multiple endings and branches.

Wait, did I miss anything? because I was excited to see the part of the image thats on this web yk? (talking about the leah looking in the mirror) or is it a part of a ending that I missed?

(+1)

The image with Leah looking at her bustier self in the mirror is only a promo, so you didn't miss anything!

(1 edit)

oh wow such a quick reply, gotta compliment the services haha, but thank you for answering.
On an another note, the game is quite lovely, really really enjoyed it, hope to see some lactation content tho, there was none if im not wrong
(and, is there any way to add the latest episode 14 part two in the already existing app? because I dont really want to delete the whole game and then download it back again)

I don't believe so, at least not with Android.

In the cruise ending, why do Grace and Laura's breasts stop growing, but none of the other girls? I don't remember you hypnotising them to stop. 

(+1)

Laura has the watch for that ending, although the Main Character is commanded not to notice. She uses it on the girls to make them stop growing.

how do i activate the walkthrough again

(+2)

This game is really good, I'm very impressed by the thought and depth in the game. It's not a short ride. I just wanted to vote for finishing Jenn ending 1 at some point please.

You've got a pregnancy tag, but I don't remember anyone getting pregnant last time I played (not long ago)

(+2)

The main path is still leading up to pregnancy content, but side endings and branches offer lots of opportunities.

(+2)

I got a ending where i knocked up laura and her sis with like 6 kids they arent shown but they mention it

I have recently started playing this game on web and thought about downloading the free version, though from past experiences data and progress tend to not save when the games get updated, is it also a thing here ?

(+1)

Depends on the platform. PC and Mac makes it easy, Android is more difficult.

i am playing on PC, so i assume data would be able to be saved when you download or update to a new version ? if so how do i do it

Once you have the game downloaded saves are kept automatically in the user/appdata/renpy/game name folder, I believe it is. Although the appdata folder is generally hidden by windows by default.
There's a forum answer for it here

i assume you just need to move the files from there ?

yep, save data i usually just data files being read by the program

Hi! Hope you're doing well!
Randomly found this game and i've been really enjoying it. 
Are there any plans of voice acting/sounds/music on the game? Was just curious =)

(+2)

Hey, thanks! Glad you're enjoying it.

No plans for sound currently. The last time I polled patrons about it being worth it to spend the time adding music and sound effects the majority said it wasn't a priority, so it will likely remain visual only. Although even if they wanted voice acting I wouldn't be able to afford it with over 60,000 lines of dialogue so far.

Still, I have fun adding music to Endowed, which to me makes sense with far more diegetic music playing in the club.

I understand the decision. While it would generally further add more enjoyment to it, after playing it for quite some time, and witnessing how much content this game actually had, i completely agree with everyone else here now.
But out of curiosity, it would probably take quite some time to even  add music to the game right? Considering you'd have to get through every single sequence etc. phew what work it would be lol.

Anyways, i love your work so far and i decided to look into your other work. Much love and stay healthy!

(+1)(-1)

Theoretically. Although it would be simple enough to pick out 5 or 6 songs and play them on a loop, which I guess some people wouldn't mind. Personally, I'm not big on game music in VNs, and I tend to mute it and listen to my own playlists on Spotify 90% of the time anyway. 

But I'd rather take the time to give each girl her own theme song and actually match scenes and moods to specific songs, which yeah, would take a while. Still, I think music has become increasingly common in VNs now. I used to never get asked about it, but now it seems to come up fairly often.

(+1)(-1)

add  Weight Gain

(+3)(-1)

Is that a request or a demand?

(+1)

😂

Where does the free version end and the premium version start? Like is there an entire chapter more? The one you worked on for an entire year? Is the Broke watch ending really the ending of that string and the premium version gives you an alternative ending? Or is it a complete chapter with still an open end?

(+1)

The premium version is early access to the latest update which is Episode 14. Currently I'm working on Episode 15 and will continue the main path beyond that.

(+2)

alright thanks, I will go get the premium Version in the next few days :)

There is a possibility that in the future we will be able to use the watch to determine how much each girl's breasts or butts will grow, in addition to being able to hypnotize rachel or beth.

If anyone is interested, I asked an AI to do a song about Hypnosis: 

(+1)

That's amazing!

(+1)

I love this game, but I wonder if there will be a path where they all turn immobile.

Is it only Breast Expansion, or is there an option for Reduction?

(+1)

Only expansion at the moment, but there will be an ending or two where the girls can choose to shrink back down to more manageable sizes.

Okay, cool. Thanks.

(+2)

I swear this game is the mass effect of porn games, it goes so hard, excellent work.

(+1)

Thanks!

Is this the finale or will there be other announcements?

(+1)

There will be at multiple more updates

There's a way to make Brittany (Laura sister) hipnotize and had bigger boobs? Because that would be neat

(+1)

Yep! It can be done in Episode 13 as long as you have the watch still.

(+1)

When playing "Two Truths and a Lie", Jenn claims "I hate pineapple on pizza" as one option, but when you pick that option, she says I got the answer wrong, and that she loves pineapple on pizza...??? I mean, wrong opinion and all, but shouldn't the text say "I love pineapple on pizza" if that option is supposed to be the truth?

(+1)

Ah yes, a double negative. Fixed!

i have a question in the sumisibe path (act 8) jenn kiss alex (in the party). This game not supposted to be ntr free? (that scene look like jenn is doing things behind theMC is back)

note: im following the guide an go later to the party

(-1)

and there was indeed a kiss (confirmed later in the game). man, why not make it optional. This makes the game have deceptive advertising regarding NTR (yes, it's just a kiss. but NTR at the end of the day).

I'm going to continue the game hoping there won't be any more minor annoyances (hope this game doesn't turn to shit)

(+1)

In the scene Alex tries to kiss Jenn but she rejects him.

(1 edit) (-3)

mmm...the dialogues didn't say that (jenn even apology to the MC). But hey meaby this is just a grammar error (I really doubt it seeing all the dialogues regarding the topic). 

Still... i will watch this game close-up went i'm playing it (i really hope this game don't turn out to be a ntr bait)

(+1)

Mmmkay

(+1)

is the In-Game Walkthrough Guide and Updated External Walkthrough Guide in the Premium Edition only does the Free Version have it to.

(+1)

The external walkthrough guide is public, so it's available to anyone. The new in-game guide is part of the premium version and for patrons as a bonus.

(+1)

is there a link to the external walkthrough guide

(+1)

Sure, it's linked here https://www.patreon.com/expandinguniverse/about

thanks got it have a good day

(+2)

I've seen you in the comments, it's good to hear from you again I hope you're doing well.

(+1)

Thanks! You as well

Any Important reason to decline her request to bang in the bathroom in EP 10?
(+1)

Nope! I'm actually in the process of reworking that section now and adding a new path there, which will be implemented in the next update

(-1)

Have you stopped working on endowed?

(+2)

i asked on discord theyre still working on next update for hypnosis thats what patrons voted for ... he said should have another update out before end of yr

Do you project to add female muscle growth sequence? 

(+1)

I don't have any plans to

(3 edits)

Alright so I'm at this part in episode six but no option is coming up to choose between them, and it is just automatically pushing me to say “why's that?” Is there any way to fix that? Or was the choice removed here?

Laura: If Grace ever gave you a BJ, she would basically own you.

  1. She already has.

Admitting you received a BJ from Grace lets Laura feel less judged, and she will agree to having a threesome with you if you don’t try to f*ck one of the girls by themselves first.

  1. Why’s that?

Still gives you the option to hook up with each girl individually.

(+1)

Not sure, I'll have to take a look. I'm guessing maybe there was a step the walkthrough didn't cover

Just wanted to say I was having the same issue.  That spot in the conversation doesn't have a choice associated with it, it just moves on.

Ah, I figured it out. The menu is dependent on whether Grace gave a BJ in the coffeeshop back in the first episode.

That... makes a tremendous amount of sense, lol.  Thanks for finding the trigger.  Love the game, btw!

(+1)

What was the update 45 Days ago?

I tried following the guide to get the longer version of chapter 11, but it's only giving me the shortest one

(+1)

How would you go about updating the game when a patch drops?

(+1)

On a computer it keeps your save files automatically so you can delete the game folder and still keep the saves.
On Android it's a bit more complicated, you have to keep the program installed and replace it in order to keep the saves. Otherwise you can find the save files and save them separately and copy them into the game folder for the new version, for which there are tutorials for Ren'Py online.

(+2)(-1)

Hope you're doing well, still looking forward to the update.

(+2)

ive played 10 hours and holy shit, this game is amazing and addictive. if you value your sleep pattern only play this when you have tons of free time!

Hey, you leave Cory alone, he has a couple momentary issues but he is best bro.

(+2)

(+1)

Excellent game, totally recommended and I loved the tribute to Chris

(1 edit) (+4)

Amazing game! is the end of the broken watch path (v1.2a) the last we will see of the really big breast expansion? Or will that continue in future updates? Hope there's more of where that came from!

(+3)

will we be getting an update soon?

(2 edits) (+7)

The latest game update just came out on Patreon, and I'll also be releasing an early release/premium version here with bonus content.
