Enter the Expansion Mansion
Welcome to Enter the Expansion Mansion, a breast expansion text-based adventure game!
In this game, you will take on the roll of a man who, along with his wife, investigates a manor home at night, four years after the mysterious disappearance of its owner.
This game is a work in progress, with more content being added gradually over time as I work on it.
I am still learning how to create with Twine and Harlowe, so the game will improve over time as my skills grow.
This site will see an eventual release of the finished game, but Patrons will have early access to builds of the game as development continues. You can become a Patron here.
If you encounter any bugs, mistakes, or general weird stuff while playing this game, please report them here.

i demand to know about the 3rd maid mentioned in the main ending
She's not mentioned anywhere else. Just meant as a teaser for the future.
a suggestion for another rout have a third android in the lab that can have her breast modified and give it to the spirit
How many ending are there ?
At least more than 10, as each route can have a good or bad end, I think.
Just wondering, how many endings are there? And could you give a specific number for how many good and bad endings there are?
Just reached the true ending, I've tried to figure it out before now, but I must have missed something because I could not reach it before reading the guide in the help code. Honestly, I loved the game, but something I want to check is if the sequel is still planned and is not a canceled project. I know projects can get canceled, and I wont be mad if it has been, but I'm just wondering if it is canceled or not.
Still very much planned. I wouldn't expect to start work on it until 2025 at the earliest, though.
Just reached one of the endings, fantastic work! The writing has been thoroughly enjoyable, the kink stuff copious and the puzzles have been quite fun.
However, I don't seem to be able to find a way to move Meloni or Helga without using up the wish. The bra doesn't seem to be an option, with Sara just dismissing it. Is there a playthrough anywhere?
I do wish you were able to make a hard save file on your computer, though. The game is pretty long, and I don't think the three soft save files in the game (which are nice) will persist between incognito windows.
There's no way to solve the Helga/Meloni puzzle without a wish.
And the save file thing is a limitation of HTML and Twine, so it will be always tied to your browser cache, unfortunately.
I've seen plenty of other Twine games that do have an option for hard save files. Is that a plugin, newer version or not Twine to begin with?
I'm by no means an expert on Twine or HTML, but, within Harlowe (the Twine coding language I'm using), the save options are limited to the browser cache. It's entirely possible that other games are able to do a hard save using Sugarcube or some other Twine language. I don't know enough about those languages to confirm or refute, though.
Ugh... Made a typo on one of the names during the part, how do I reset it?
The circular arrow in the sidebar will let you reset the game. That's the only real way to change the names, unfortunately.
I can't tell which is better, "eager to explore" or "in a fairly good mood" with Sara's happiness. Which is it?
Eager to explore has the best results for expansion content. Fairly good mood is her default.
Where is the download for 1.6.1?
Due to the way itch.io does downloads, you can't download the most recent version that plays in the browser. You can, however access it on my Patreon. Version release posts always go public when itch.io gets updated.
is there a way to win without using a wish?
There's no way to get the "best" ending without a wish. You are able to leave and return Kirsten to normal without using one.
Cool, just making sure i wasnt missing anything
It might just be me, but I haven't found a way to boost Sara to her absolute maximum size and still get the best ending.
Here's the things I do know on how to increase her breast size:
So I'm wondering if there's something I'm missing. Especially since it feels a little disappointing that you can't get both maximum size and best ending.
Unless giving Meloni breast milk (before fertilizer) is supposed to make it +4 sizes and it's just not working.
It is not possible to get to max size and also get the best ending. I wanted to include something for those who chose to forego the best ending to still find a fun thing.
Unfortunate.
Still, a very complete experience. No complaints on the writing or how things go.
Only suggestion I'd have from here is the best ending including a new code to be put into the keypad that does let you get both maximum size and the best ending. But it'd require already being as big as possible for that bonus to work.
is this game getting any more updates and are there gonna be more games ?
It will get one more patch that fixes a bug or two that were preventing some content from being accessed (so kind of getting new content), but there will be no further content updates. Just occasional patches.
I'm currently finalizing the first Version Release of my next game for Patreon supporters, so that will show up here in around 6 weeks (it's less an adventure game and more a pseudo chat-bot style experience).
After a few updates to that game, I'll begin work on another text adventure like this one, with a future sequel to Enter the Expansion Mansion planned, as well.
Heya! Just finished the game to the best of my ability (trying out different combinations of actions to see how much things change, as well as the differences in the ending sequence based on sizes) and I've got to say, this was incredible! It's worth mentioning, I loaded my save file from the last time I'd played and when I went into the final area, moving to look at either the sphere or the tube spat out an error code, but starting from the beginning didn't seem to do that. Who knows, this might even already be fixed in 1.6.1, but there's no harm in letting you know :)
so what is the code for the Easter egg ?
Will 1.6.1 get a public release?
Yep! April 14 and 19 are the dates for V1.6.0 and V1.6.1 public releases. Any future patches will likewise get a public release.
Awesome can't wait to check it out!
This was great! All of the new endings and variants, the increased size, improved UI (saves & loads & info) AND the special easter egg for entering the key when you shouldn't know it? Icing on the cake! VERY excited for the next update, and the final release :)
Hey, thanks so much! Glad you're still enjoying it! It has been a super fun project.
please tell me how to get the Easter egg from entering the key please
you need to play and discover the code to the keypads. Then start a new game and enter the code before you actually learn it. You will get a secret ending that is technically a continuation of another bad ending you can get.
so what is the code please tell me
I wonder when there will be images
There are no plans to include images in the game. The cost to commission the art and complexity of incorporating images to account for the various possible paths would simply be prohibitive.
how do you get all the new endings ?
All of them stem from the Devil in the Library. Many off the wishes will either have no immediate effect but will add an epilogue to the story as long as you don't get a "bad" ending. Others will send you directly into a new ending.
Some wishes are only available if you've explored enough or the wife is big enough, so do plenty of exploring before you make your wish.
HAWT AF.
Decent content and story to go with the hot stuff too.
Thanks! Glad you enjoyed it!
is there images
No images as far I´ve seen
Correct. No images in the game. I have neither the art skills nor budget to make it worthwhile to pursue adding art, sadly.
Well I got good imagination so I can visualise it in my mind and if I was better at drawing I would love to make the art but I´m no better than a 4 year old
Same here. Me draw pictures with words. :D
I´m wondering something and I´m a little clueless what to do about it and that is the "brew" that´s in the bathtub on the 2nd floor? do I need to do something before smearing it over on the wife? or is it just there as now we are slightly dirty from that "brew" in the tub?
PixAi lets you create images for free using ai, i'd say that's the best alternative for now, love the game btw
In no uncertain terms, I am 100% against the use of AI programs to create art. Full stop.
understandable
I’ve thoroughly enjoyed stumbling into this! Eagerly awaiting further updates. If I have one request, it would be for lactation to affect more things. Like I really like the one scene with Meloni’s pot that it unlocks, so just more of those kinds of options. I also think it’d be really good if getting it early affected how subsequent expansion sequences play out. This started out as a general “more responsiveness to doing things in different orders,” but that was really the main one.
I’m sure you’ve got that on your to do list, I just thought I’d voice support for it. 👍🏻
There still isnt a code implemented?
Next major update will have the pieces to get the code. The following major update with add in the content that will be unlocked by the code.
I have reached the point where I am supposed to bring Helga to Meloni, but I can´t find a way to progress through the story. Am I missing something, or is this the furthest I can go in the story for now?
Afraid you're stuck until the next update.
Thank you for the clarification and sorry for the late response.
Well, it's the latest patch and I'm once again stumped on the specifics of what to do, although I suspect it's something from last update that I still don't know how to do compounding the problem, as I can get the Wife to tier 4 and Helga on the charger, as well as knowing that the last level of growth is more than likely something to do with Meloni, and yet I've run out of rope. I will say, the new content that I've been able to play through is very interesting! My thanks to you for the continued development of this game, and fingers crossed someone, dev or otherwise, will help me with my plight.
If you're able to get to tier 4 of growth, I suspect that the Meloni growth is what you're missing. Try *not* using the formula in the sitting room, but instead just taking a few with you when you go to revive Meloni.
Glad you're enjoying the game!
EXCELLENT! Much appreciated :)
I can't seem to get past the 3rd level of growth (F-Cup I believe). Is there something to be done with Meloni to get to another level?
Yes, it has to do with Meloni. I will not offer any hints though.
I figured it out, I need to read more carefully next time. Thank you!
I'm guessing the code for the keypad wasn't implemented yet. Found what seems like a 5th level of growth for your wife, at least from the description. Although the process for that also gives me an idea for a potential sixth. Will save the idea for now, partly to avoid spoilers.
I do want to suggest renaming the halls upstairs to "north hall" and "south hall" or "east hall" and "west hall" because trying to navigate them as just "left/right" is a little difficult due to the relativity of left/right.
I'm excited to see more progress with this story. I definitely want to see more and perhaps even a few more "bad ends", like perhaps the wife getting addicted to being milked or having a continuous growth so extreme she destroys the house.
I can't find anything about a code for the keypad. is it in the game yet?
it's not there yet. It'll be one of the final things to be added.
To make sure I've seen all there is to see, the biggest you can get your wife is F cup, yes?
Correct. The third expansion sequence is as far as you can go in the current release.
Can you add images
I don't intend to include images as it would cost far too much to commission the needed artwork for each possible scenario that I would want images for, unfortunately.
ok
I like it, a spooky atmosphere is always good for a game like this.
Met the maid robot the first go through (found and used the gun path). But on subsequent runs through I was never able to see her! I thought I first saw her in the foyer, but after the foyer is just a room that leads to "end of demo" room stubs. Love to see this game though, short but sweet :)
The maid is only out and active if you happen to do something specific that causes her to be there.
She's a maid/house servant after all. She might be forced to leave her quarters if she is notified that there is someone at the door...
Ahh very good, that's smart!
How do you convince her to drink the potions?
You'll need to sneak a peek at Kirsten's chest at the start (to make her jealous), then you need to make sure you climb the trellis first, so you don't piss her off. She is then more amenable to drinking the potion.
Can you please add my game to your collection?
So I think the endings are
Am I missing any? Is there any use for the fertilizer?
There's a second pissed off ending where you don't try to use the raygun.
There's no use in the demo for the drill or fertilizer. Those are the for future content.
Great fun! All that you need is a save system and you're ready to keep going! Looking forward to continued builds of this and whatever else you decide to make in the future :)
