is the game done or is there more to come?

(+1)(-1)

I want this game to be in sandbox mode, so that you can have sex and other things as much as you want, I also want it to be possible to choose sex with or without a condom from the very beginning, I also want it to be possible to have vaginal sex and pregnancy.please do this

When is the new update coming?

(-2)

This isn't my kink. It's not bad, but it's just the same scenes over and over again. And the same text to accompany those same scenes over and over again.

From my point of view, it's more like the tech demo that the dev made about the game that he would like to make, than an actual game.

If story isn't of great concern to you, AND if this is your kink, you will probably like it. If you want a tight story ( or ANY story really), you will be disappointed.

The girls are cute enough. Just don't set your expectations too high.

Is there SSBBW in here, cuz the other game treat it on fantasy and I want IRLG... Game. In Real Life Game is there really SSBBW innit Bladerune9?

Loved this game! Haven't gone through one this quickly haha. Krystal and the mixing lady (forgot her name) are my favourites, dem belly! 😍

very fun. Krystal is very hot. kinda dialogue heavy.

Love the game, hope to see Heidi experience some growth, and hope the minigame gets a little simplified, can be a real hassle at times. But love your games, they're the best!

(+1)

it would be funny if after giving Heidi the formula, she shows up just incredibly fat next time cuz she used the formula unsafely.

(+4)

Jesus christ that mixing mini game made me delete the whole thing after about 40 tries. What a pain in the ass!

what is the correct outcome on the mixing minigame

(+4)

Could you add Female Muscle Growth in future? **

(+7)

I might add a FMG alternative recipe to the mixing minigame for Catie.

I loved this game and i was wondering when is it going to get a update.

(+3)

My main focus is on my other game, Fattening Career.
So whenever I finish a Fattening Career update, I put a few days/weeks into developing this game further.

If you don't mind me asking, what virt a mate morphs did you use for the models in the game?

(+2)

Way too many to list honestly.
Lately I have been using some morphs made by HevieState3D. These aren't made for VaM so you'll have to convert them to G2 and then port them.

(+2)

what about FMG?

(+1)

I might add a FMG alternative recipe to the mixing minigame for Catie.

The 3rd one in the mixing game makes no sense or is way too difficult to figure out, I've tried many times and cannot get it at all. 

(+1)

Thank you for your feedback, we'll change the mixing game in the next update to be better.

I did end up getting it - the first 2 seem to be counteracting the problems in the notes, while the last one you have to pick the one that furthers the problem from the notes. 

(1 edit) (+8)

I've made a cheat sheet for myself, hopefully the dev doesn't mind if I post it here. The harder stages are after the break if anyone doesn't want them spoiled. There are only five possible sets of rules for each stage, corresponding to each of the five ingredients. Figuring out the third stage was mostly trial and error.

STAGE 1
hand mix + too thick + reaction too high + use heat = water
use heat + reaction too low + bitter taste + stable = veloute sauce
stable + too thick + hand mix + reaction too low =  milk
hand mix + too thick + reaction too low + use heat = butter
hand mix + reaction too low + stable + too thin = cream

STAGE 2
no heat + high pressure + stable + multiple stages = amylase
high temp + no pressure + single stage + no bad taste = cellulase
fast reaction + no heat + no bad taste + single stage = luminase
no heat + slow reaction + no bad taste + high pressure = pectinase
no heat or pressure + no bad taste + single stage + reaction too low = mellinase

STAGE 3
no weight gain + no hunger + good milk + no libido = anthocyandin
average milk + no weight gain + no hunger + optimum absorbtion = catechin
no sensitive/libido + average milk + stomach unchanged + weight gain = daidzene
no sensitive/libido + no weight gain + low milk + prefer new serum = lycopene
no sensitive/libido + average breast + average milk + increased consumption = hydrolysate

Oh my GOD! Thank you! I just don't want to think and just enjoy the game the right way

(+3)

Im loving this game I think its even better than fattening career given how immediate alot of the changes are, the pacing out between stages is done really well too and I love the new dialogue and interactions here. Looking forward to even more stages and more events with the other characters. Catie is a great addition.

(+2)

Thank you, I'm glad you like the game!

(1 edit) (+2)

 I wish you will create a game where the assistant is the main character. 

Thank you for the game and the beautiful assistant.

(+1)

There is some stuff planned with Karren in a later update for this game.

This is simply amazing! I can't imagine how you find the time to both rework this game and continue fattening career, but man, please keep going! You have incredible talent: the girls look amazing and their progress is incredible. Heidi's teaser already made me love her. 

There are a few small bugs in this version (I'll try to post them on the discord), but they're nothing compared to the amount of work done. You're awesome!

Thank you, I'm glad you enjoyed my work.
I'll await the bug report in discord so I can get those fixed for the next update.

Is there a way to do the sex scenes with them at their max in 1.6?

(+1)

You get one regular milking event with all of them at their max stages before the game ends.

Thank you, love the update btw!

(+1)

More gaining. I'm in

"Pump them full of liquid" so is it by design that some of it looks more like fat? Haven't  played the game btw, just pondering.

(+1)

Some liquid is absorbed into their bodies and turns into fatty tissue.

Could you at some point in the future add these girls (or at least 1) to Fattening Career? They're really well done and I would love to see them added even if just as a small side-story or something.

(+2)

Actually, the emo girl shows up on the background when you hang out on bunny bites with Hari lol

(-2)



the best is the beautiful woman with darker skin the first only has breasts and the second only has a beautiful face the third is the best she has sexy hips and those big breasts are what a woman who is a goddess should look like

(+1)

Hello, hey, how do I create games like the ones you make, what programs do I need?

(+2)

In order to make the game itself you'll need Ren'py, which is a visual novel engine.
And to make the visuals I use Virt-a-Mate, but there are many options to make visuals.

¿Así que ahí puedo crear mis personajes?

(+4)(-1)

Fun but kinda repetitive.

(+5)

Sarah is my favorite hands down, but I really like how Krystal goes from kind of skeptical and only wanting fast results, to being totally okay with being bigger in the stomach area than the chest and actually crushing on the Main Character. Very nice development there. 

I just love how happy Sarah always is and you really can't overlook those purple eyes just staring into your soul. 

(+8)(-1)

Krystal's the best. 10/10

(+2)

Fantastic work! Unfortunately it appears that the animated parts are instantly skiped on the android release. Nonetheless, thanks a bunch for making this!

(+6)

Holy cow!
How are you able to put amazing stuff like this out?! And in such short time! Your talent for making games like this is truly admirable!

(+5)

Glad you like it. I'll do my best to finish this game after I'm done with the next Fattening Career update.

(+2)

That's exciting. I didn't think this would get more content. 

(+4)

Good job with the effort, definitely worth it, keep it up :) 

Is this Vam?

The visuals are made in VaM.

This is one hell of a game! My one complaint though is that the sound doesn't seem to be working, at least for the Mac version. Very excited to see what you do next!

Sorry but there are no sounds in the game.

I can't download it on android

It loading very slow (it weight 2.2 GB)

And when it downloaded as file, it minute load app but after this crash

(Sorry for my English)

(+1)

I'll have a new build up in 30 minutes. This will shrink the game down to ~1GB.
Hopefully that fixes your issue

 no, it didn't help, now I get to the moment of "install the application" but when I click it says "the application is not installed" (maybe it's because of memory, you have to try to see something else) ((googletranslate))

(+1)

Maybe this video can help?

Video Link

(+1)

I just deleted some useless apps as "calculator","clock","camera" and other 

And it helps

(+2)

You got to push them, you got to push them, you got to push them, you got to push them.

Am I missing some amount of player agency? It's annoying AF getting incessantly nagged to do something I literally can't do.

(+4)

No you aren't missing something.
Due to time constraint(this was made for a 2week gamejam) I had to release with unfinished dialogue which made Karren more annoying then intended.

(+5)

Krystal really is the ideal woman ngl

hey bro tommorow is the day fattening career new update drops right?

(+2)

No it drops on Sept 1st

o i see

(+2)

Another game! This is going to be good I can feel it!
