I think you should add Chinese.
This is an amazing game. Some graphical glitches I have seen but nothing too terrible except 1 so far. With Brandy in the amazon position it's like your balls are the base of your shaft like a gear shift or something. Overall love the storyline so far and am on my first play through.
Thanks! Glad you're enjoying it
Why does Haley look green? aka why is she a Lizard woman?
When she was younger she went to Solvalley school and got radiation poisoning, probably
shes got lizard skin and lizard eyes
I'll take you word for it, as I don't spend a lot of time around reptiles or dinosaurs
Is the game dead?
Alive and growing my friend
When is the rest of Episode 15 coming?
theres also an instance where ash and mc talk about doing it again before doing her for the first time in mc's car. Also before meeting laura in diner mc is constantly said to have the watch when he does not.
Thanks! A few of these are deliberate (pobody's nerfect, for example), but I'll take a look at the others.
after laura incident in gym talking to daphne MC says he pulled out watch when he did not he used phone and larua used the watch. Also during talk MC said he was thinking why they all still follow his commands, well its because he asked Ashley's subconscious this morning and she told him lol. Its odd how many inconsistencies are starting to pop up in later chapters
when you meet 5 of the girls in the gym mc talks about daphne but says Laura commanded daphne when it was mc?
at the end of grace time at house MC says he's gonna leave then grace asks him to leave then he says hes gonna leaven then in away like she hadnt just asked him to leave, shes tells him to leave again, its just a broken part of conversation lol
yo during talk with grace at her house she says Pobody's perfect instead of Nobody's perfect
Is there a replay scene option? or maybe a walkthrough that tells us when we will get a scene so we can make a save beforehand?
Making a replay gallery has been on my todo list for a while. I'll be working on it for Endowed first, as there are far less scenes to combine with it, eventually getting it going for Hypnosis
When is the next update
Question, im new to the game but I can't get the Daphne ending. Do you have any tips ?
Yep! It's not available yet and will be in a future update.
Hey, I've reached episode ten, however I seem to encounter a problem after I roll past the introductory scene for it. Could you help me figure out how to fix it?
Happy to try! What's the issue?

I just realized I could ignore it. I'll hope it doesn't prove to be fatal for the playthrough. ¯\_(ツ)_/¯
I'm quite happy this is back
Seems the free version is no longer banned! Good news for anyone who isn't able to spring for the premium version.
Hey this game was taken down from Itch.
有中文了踢我一脚谢谢你
Am I right that the girls on their way home from Korea is the end of the bazoongas assets story? There will be no more updates to that story arc, where the girls mammary are all humongous?...
Yea that/those side story lines have concluded from what I understand.
Where is the walkthought?
I just got to the Ashley titjob scene, WHY DOES THE DUDE LOOK LIKE ME?!
Is the paid version of this no longer getting updated?
The premium version gets the latest updates as soon as they are tested and ready.
should there exist any cumflation/inflation vn tho? like would not be possible for 3d to make?
You mean are there other games featuring cumflation and inflation? There are a few, and the first one that comes to mind is the game Insatiable which is linked under "similar games" on my creator page.
welp if project realism included vore and cumflation as main and not sided option
dang it the stupid pay system for this one made me by the unexpected game by thes people twice instead of this
Ah, sorry to hear it. Not sure how that happened though. Were you trying to purchase the premium edition? If so, I'd be happy to send you a download key.
what's done is done. I'm good
Little bug when first meeting Brittany: Laura told me it was nice Grace called me her boyfriend, but she didn't (I'm her enemy this run).
Game was an absolute blast. Not only were the girls fantastic, but the MC was written really well and I liked the direction it went.
Really looking forward to see where it goes.
Thank you! It always makes my day to hear kind words.
Y only Android is 1.3 GBs and others are 3 GBs? 🤔
To make it work. Android has a 2gb limit.
So, content was removed or game version is down-graded for the Android version to allow the APK file to not turn into an XAPK file(APK +OBB)?
The images and animations are more compressed.
Would you ever add an option to hypnotize people like Ashley's mom or possibly other side characters into joining the harem or even making their boobs and butt bigger.
If this game is in the same universe as the White Russian game. According to lore, is the watch some demon artifact?
Ha! Somehow I didn't see this comment until now. I like the theory, and I think could maybe hold weight? Personally, I've always viewed the watch as only working so long as the character believe it works and not necessarily having magical powers beyond a basic placebo effect. First Leah believed the watch was working, then all her classmates did too. This is why other objects wouldn't work, as the characters didn't believe in it.
i like the game so far but i would like some control over their breast sizes and how big they can get (since you say this is for both gentlemen and perverts but seem to only cater towards perverts), because if i wanted breasts to be unrealistically huge i'd go play Fantasy Opposite with The big bad wolf's daughter's massive ass and tits or cinderella's daughter's giant tits. but that is just my 2 cents and i'm still gonna play even if i can't stop them from growing.
Originally I planned to make the girl's sizes optional after a certain point, but soon realized making double the images and animations to account for that would not only double the time spent on visuals, it would double the game's size.
That made me change course and focus on making it optional for the endings. The Broken Watch Branch accounts for this, and was voted on by patrons to complete first, where the girls all continue growing uncontrollably. Several of my patrons say it doesn't go big enough, but that's a topic for another day.
Now back on the main path there are around six updates left, and will be multiple endings throughout. At least one ending will feature the girls with reduced sizes to give a happy ending for those who don't enjoy their ladies quite so... blessed.
Cheers!
cool and even though i prefer small breasts i'll gladly enjoy big breasts as long as they stay within realistic sizes and not whatever "d" breasts that the big bad wolf's daughter has in fantasy opposite ,which if you can't tell take fantasy characters and does a couple genderswaps but some stay the same (it took me actually playing he game to understand the full scope). i want to say that they are either quadruple or quintuple D.
how do you get them to not have tits larger than their heads? I've done 3 runs specifically not wanting watermelons but they always end up with them.
nope, larger breasts should be admired and appreciated, plus they look so cute and adorable with such large breasts, you just have to adjust to it~
Best game i have played, hopefully you continue with this game! i really enjoy it and no other game really satisfy as much as this one.
Thank you! I appreciate it.
I have an issue with the game, the game crashes surring the sex sceen with Grace in the car after they went for an ice cream after he met Laura in the restaurent for the "i'm sorry" talk
i tried to restart the game but it crashes on the third step of the cowgirl animation everytime
Thanks for the report. Is that for the PC or Android version?
Its on PC version
What is the "True route"? The Broken one with
Super big expansionsor another one? (I said that cause is the biggest one so far with history)The true route is through our Lord and Savior Jesus Christ who died for our sins so that we could have eternal life.
lol their are many routes and many religions but the one that they all believe in for all eternity is . . . . . . . . LOVE!!!
am I the only one who doesnt have any sound? is there a fix for this?
Will there be a gallery to revist scenes added to game?
Is there going to be a Fetish added orienting around muscles and fmg?
genuinely really enjoyed this game, I got invested in the story and the relationships between the characters. The dialogue is interesting and funny, the creator of this game has a pretty great sense of humor. Looking forward to seeing the rest of the chapters play out.
is there an up to date walkthrough that i just cant find
Yep! Here's the link
anyone else have no sound in the game at all?
Yeah same for me
xd
So, I've been a big fan of this game for the last few years, and I would play it off and on, just to wait for major updates and continue playing whenever I got the chance. I'm a writer of my own, and I love what you've built, so if you everwanted assistance for writing, I'd love that.
Currently, my only question stems from Laura's mind-control. As there are two major paths (badass guy, or good guy), I didn't expect Laura's mind-control to end up causing the MC to unintentionally mind-fuck some of the girls, and it ended up turning me off from the game when it was revealed. In Ashley's case, where she won't let her mother be touched and you have to unknowingly mind-fuck her to open that path, and in Aera's case, where her path is completely closed if the MC doesn't stupidly realize his words can mind-fuck Leia.
As this all occurs in Episode 14, I don't expect this to be the very last version of these events, but I wanted to ask: Do you have plans on furthering the good guy parts of these routes, so some things may still be attainable without this unintentional mind-fucking, or is this going to end up as a result of the story that can't really be tampered with?
I absolutely adore this game. You've done amazing work here!
Thanks!
It doesn't seem like it so far, but both Beth and Aera's paths will still be available when the MC continues to be a good guy. He'll just have to work towards it.
