In a world where some girls are massive in many ways, one young man (or futa) finds out they may be more than they seem.

I also wanted to report.. after this scene here, Everything beyond it is just a series of Erorrs
Wanted to point out a little mistake I noticed lol, Shouldn't the MC here be same size as Kammy?

The game does not work. The archive can’t be extracted normally. I used 7zip, and it does not open, because there are not the “lib” and “python” folder in there. (Problem occurs only in the pc-version I’ve tested so far…) Please fix it!
Game crashes when futaonly mc grows from drinking multiple pistol milk
For some reason i cannot save the game no matter what i try, sort of error come out, does anyone know how to fix it
is impressive that 4 release and still end in the same way maybe for 2035 we can see the continue of the story, keep giving him money btw
When will the game be finished with the female Futa routes
Is there a changelog or updated route hint for 22 or 23?
you should go ATH's patreon to know more
the update is good n all but u couldve went more into the size steal serum route more than telling her the secret route since she hates the mc
will there be sex sounds? love the game but that will make it better
I am begging you to make a roadmap for your game
This is a total mess and each updates makes it even more confusing!
Finally an incoming update after so long
. Is there any content about pregnancy?
not currently, but it seems like it'd be possible with at least one of the characters
Dev creates a great game with a unique premise but proceeds to dig themselves too deep on just how many branching paths they create. Then, instead of pulling some of those paths and narrowing their vision (perhaps saving the removed ideas for other games), they all but abandon the game and proceed to start up several new projects instead, keeping their supporters just hooked enough with content so that a "soon" is all they need to believe the original isn't actually abandoned. Sad turn of events, and all too common.
when is the next update? please dont be discouraged
rip?
Pretty much.
any plans on a new Update?
new update info when
any foot crush scenes?
will game be added back to itch
When is the next update?
is it just me or did all the adult games just vanish
Hear he Hear he
itch.io just delisted all adult games from search results. This means nearly all traffic for your games is gone. There have been people whose titles have been deleted altogether as well. Spread the word, this injustice must not stand!!! You still have your Follows available. Reach far and wide for the others.
which of the 3 versions feels the most right/best to play?
I go to my save and it crashes with the error screen to ignore, rollback, open, and close options and when i click ignore it restart the game but not to the very beginning and when i go to start a new game i can not start from the very begining. I lost content between .17 and .19 and i do not know how to receive that content because i am very confused on what happened and since i can not start all the way back at the very beginning then i do not know why i should continue this game even though it is a very great game.
every time i try to open a new save it says:
While running game code:
File "game/scripts/LanguageSelect.rpy", line 5, in script
jump English_Start
ScriptError: could not find label 'English_Start'.
idk what to do
I'm not sure if this is my fault, but I can't get the new update to work, extracting the file keeps getting errors, even when I use 7zip it still doesn't work, is it just me or is anyone else having this problem (full disclosure, my computer DID crash while I was downloading on Mega, which is why I think it might be on me)
Well the update was short, but it did let me know that I missed the best route at some point (my nemesis, hiding the grow route behind the shrink dialog. lol). But damn is the "small" content there good. I'm not a big VN fane, but I love this one. Looking forward to the next one.
Today's the day!
What is new in the new update? I can't find what is new.
I believe it goes public tomorrow.
I can't wait till we can make Kammy like she is in the Main Menu screen
Don't have the wrong expectation going in. This isn't a game, it's a story (like you'd see on pixiv or something), perhaps a good one if its your thing. Just don't start rapidly clicking through expecting to be given control eventually. I think having the right expectation greatly improves the experience. I know I might come back to it later.

A Growing Adventure: The Expanding Alchemist
update?
Awesome game!❤️❤️😍😍
10/10 💯
Great story and artwork
I'm definitely looking forward to play the next update. 😁
Can I ask you a question? It may sound strange, but...when and with whom can I start a relationship? Simply...they often bring up the topic of children and pregnancy (or is there something wrong with my eyes) that I already want to see something like that in the game.
I am looking forward to the Chinese version
Is there any changelog for 0.19? I'm wondering if it is worth to buy premium :)
in any case, it will help the developer :)
Add sound effects 4 the scenes please
I personally would like to see the MC grow more, along with more kinky ways to get pollen.
