A downloadable game for Windows, macOS, and Linux

Have you ever wanted to see a beautiful woman slowly grow into a much curvier version of herself?
Then you’re in the right place.

This game tells the story of Luna (or whatever name you give her), a normal university student living a quiet, ordinary life. She studies, shares an apartment, and follows the same routine every day… but deep down, she feels like something is missing.

Everything changes when she stumbles upon a strange shop that doesn’t quite belong in the real world. Inside, she finds unusual ingredients, cryptic recipes, and the possibility to create mysterious concoctions that can alter her body in unexpected ways.

What happens next is up to you.

· Features

  •  Progressive body growth system
    Increase different parts of the body independently (breasts, thighs), choosing when and how Luna changes.

  •  Interactive crafting system
    Gather ingredients, follow recipes, and experiment with potion creation.

  • Time, money & survival mechanics
    Manage daily life: eat, rest, earn money, and plan your days carefully. Neglecting yourself can have consequences.

  •  Slice-of-life hub
    Explore the apartment, the city, and other locations while seeing how Luna’s changing body affects everyday situations.

  • Light-hearted tone with NSFW elements
    A mix of comedy, casual moments and teasing situations themes that grow gradually over time.

  •  Player-driven customization
    No fixed path: your choices shape Luna’s appearance and the way the world reacts to her.

· What to Expect

This is a slow-burn transformation game focused on progression, curiosity, and player freedom.
Changes don’t happen all at once — they build over time, making every upgrade feel earned.

There are no complex branching routes or romance paths (for now). The focus is on personal growth, experimentation, and enjoying the journey.

· Content Warning 🔞

This game contains adult themes, suggestive content, and body transformation elements.
All characters are 18+.

· Development Status

This game is actively in development.
More content, transformations, events, and mechanics will be added over time. Also there might be some bugs.  Although I have tested it several times, there may be some interactions that I have not yet tested. So feel free to tell me in the comments every bug you experience.

Feedback is always welcome!

I plan to do it, but first I wanna make sure to build a good base for the game

BUG: Whenever Petra would comment on my size, she'd keep looping her dialogue until it was time to sleep. Not only does this waste the day, but I can't give Petra the Growth Infusion.

Can you pls make IT so you can Play it in the phone

I really like this kind of games! ill follow to see how this game grows nicely ^^

(+8)(-4)

are you going to add fmg  ak female muscle growth and maybe height or futa aswell growth 

Petra's growth is actually height/size growth but I first have to fix the bugs and also it's not that noticeable for the moment

AI slopes everywhere.

Well, I only used AI for the backgrounds, the rest has all been done by me

Is it possible to play this game in future updates? (On mobile)

The game has potential but it's frustrating in a number of ways. First, when I buy a recipe there's no way to read to know what ingredients we need to buy. Second, there's no way to see what we already have in our inventory. Third, sometimes when you try to craft a potion and you don't have ingredients, it just kicks you to the hallway with no explanation. Fourth, as others have mentioned, there's an endless loop between Luna and Petra that eventually kicks you out of the game.

It's a good idea for a game since I love breast enhancement games, but it's frustrating at this point until the above issues are addressed.

It keeps crashing to the main menu and sometimes it even happens right the second day

Have you read the instructions I give after the intro?

(+1)(-2)

Is there a way to add music, sfx, and a translation? Maybe german? I could make a german translation <3

I don't really know if I'll add music and sfx because I don't have those resources, and as I don't plan to get money of this game, so I probably won't add it.

And about the translations I do plan to add some, but that will be later on. For now, I want to focus on building a good base for the game.

I could compose music for you… The best is: you don’t need to pay anything! You need only to credit me ;)

Oh well, I didn't know you made music, so if you wanna do it, I can give you my email address

Game crashes to main menu after switching to modeling and trying to sleep.

Well, that's strange, because I've just tried it and it works, please give me more info (stats, actual job (if you have not quit your actual job yet) and so on...)

I think for all but one potion, instead of giving you the list of what you need, it just skips ahead if you don't have the ingredients needed. I also don't know what the third potion is about, if it's just not implemented yet. 
And after the first time I talked to her, after which I think I used a potion, I never managed to talk to her again without getting looped endlessly. 
It also felt like streaming earnings didn't improve much at all from reading. And I'd have expected it to improve with potions as well. 

Interesting concept so far, looking forward to updates.  

(Also, it would be appreciated to know how many ingredients you actually have at a given time.)

I'm also getting stuck in this endless loop

For some reason i get sent to menu when i finish day 7

Basically if you skip eating you lose, which sends you to the main menu. Ngl it's not a particularly interesting feature atm.

I'm confused, I try to craft a potion and it just boots me to the hallway. No confirmation that it worked, nor any option to use a potion I've crafted. Heck don't even know how much of which ingredients are needed to craft, and no way that I've found to pull up the inventory. At this point I'm clicking buttons blindly. Can someone explain what I'm missing?

You don't have enough ingredients. Most of the "here's what you need" texts are missing or bugged.

yeah seems that after the first grow you get a dialogue loop with Petra, and if you use a level 3 potion you get a dialogue loop with Gwe

(+1)

Not sure if I'm softlocked but choosing to create a potion just leads back to the hallway

Oh that's Strange, can you give me more info? Stats, which kind of potion, the level...

(2 edits)

From my experience this is happening with any potion that you don't have any amount of one of the ingredients for/ dont have the recipe for (not really sure on ingredient amounts as i couldnt find anywhere to see what you currently have)

I have a save before i bought the growth infusion recipe and another after i bought it and after buying a bunch of elixer of temptations where both the growth infusion lvl 1 and goddess curves lvl 3 are jumping to the hallway

Edit: I was going to check on the growth infusion potion after buying a growth essance the next day after work, but the game boots you back to the main screen on day 20

(+1)

I'm also having this issue while trying to craft Lv. 1 BustBloom. I'm not sure if I'm just not meeting requirements because neither the requirements or your current inventory are listed anywhere as far as I can tell.

(+3)

This game has a lot of potential!  But as others have said there is an endless loop between Gwen and Petra that halts progress.  Other than that it's a great start!

(+1)

It also has a chat loop with Gwen after you use the Goddess' Curves potion...basically game is more-or-less locked at this point since both interactable characters are stuck in a loop

(+6)

After growing you end up in a loop with petra and cant interact with her anymore since the chat repeats. Same with Gwen afer she tells you she has different potions. 
Besides that, great game :)

(+1)

have found a way around or do i just wait for a hotfix?

(+1)

i just guess we wait for a hotfix. It was the very first release so nothing to worry about. If you find more just tell the dev, pretty sure they appreciate the help :)

Thank you for your feedback! I'm already working on it and it shouldn't take me long.
