Press-Switch / Illia's Mansion
by Skiegh

Press-Switch is a game designed by Skiegh and is primarily focused on Body Swapping but with quite a numerous amount of other forms of TF and things of a similar nature. It is a Visual Novel style game which, while, on occasion will follow the typical VN format of a linear storyline, will more often than not, lead off into entirely different tangents with each decision made. You can expect a lot of dead ends, a lot of poor writing, and an author who doesn't care about either. Enjoy what's there, this is my free time's free time project afterall.


Illia's Mansion is an offshoot, somewhat non-canon route for P-S which was never going to see the light of day until... it did. Mika Greenfield, through a very silly non-canon way acquires a board game capable of changing the world around her. She then proceeds to invite her friends and family to play with her and chaos ensues.

You take control of Calvin Hintre, an evasive teenager who finds himself observing others more than engaging with them. His people watching habits leave most of his time spent in simple wonder of situations to be -- of conversations that could be had, but never will due to his lack of assertion. This "if they don't approach, I won't either" kind of mentality leads him to live a very isolated life, with only those willing to force their way through his bubble capable of wrenching him from his otherwise boring existence. New possibilities come knocking however...

When a passing truck nearly flattens him, a stray bit of it's contents falls loose from it's rickety tail. Inside that unmarked package lay a device capable of changing the very people around him in ways he never could've imagined. Now he comes set on a dilemma, change others or himself, and how, and for what reason? The moral dilemma of this comes to shape the entirety of his life from then on. However, the device came riddled with warnings, and with it's mysterious properties, it may only be a matter of time until his curiosity leaves him hurdling towards his own bane.

Press-Switch 0.6a
Version Size difference
v.5c: 43,221 screens (average of 14.4 words per screen) (total of 621,814 words) (266 menus)
v.6a: 56,821 screens (average of 13.0 words per screen) (total of 737,223 words) (301 menus)
You may notice the word count is not significantly higher, this is due to me removing the unseen content from this release. Had I kept that in, the word count difference is about 300~400k. This update is about as large as 0.4, and like 0.4, most of it's content is one location in the game. Though this one is uh... less of a confusing mess.

What is new?
- New Path: Family Swap (Ciel). The major focus of this update, which focuses on Calvin switching all the bodies of his family in hopes they learn more about each other. Things do not go exactly as expected, and Calvin is forced into a scenario more stressful than he originally planned. This path is not complete, but the conclusion to certain variants will be coming in the updates after this one (much smaller). That said, there is a good amount of content and plenty of endings to find, even if no "true" ending is in the game yet.
This new path is not finished, and the true endings are all pending conclusion. You can expect those endings to come in shorter time frames than this update. I will likely release each one individually. I personally felt there was enough content to warrant a release, and I was also feeling myself rushing from wanting to get content out, so I decided in order to not see a drop in quality to release now.
- Path Revamp: Trio Swap. One of the first paths of Press-Switch, where Calvin, Mika, and Ashley switch bodies has been revamped and rewritten, or rather... the introduction is written. It only lasts until gym class, so it's not large, but it will serve is a nice launching point for a future update.
- Old Content that was removed is back in the game, this includes the Eliza path where you clone yourself into Elena, Eliza's new twin sister. This also includes 0.4, though I can attest 0.4 is not entirely working visually. Multiple images are incorrectly placed due to changes in sprites since that version and this. One day I will perhaps fix them. For the best experience for 0.4, I suggest the original version, but this one should be mostly functional besides a few visual displacements and possible wrong expressions on characters.
- Mild alterations to multiple paths for consistency.
- New UI
- Finally updated to a modern version of Ren'py, even if I'm still stuck at 800x600 (maybe someday).
- Multiple new screens, including a new DSM screen for the device itself. This is only introduced in this version, but I plan to utilize it more in the future. Even if it's mostly for tactile affect.

What is coming in the next updates?
- An ending to one of the family swap variants.
- Possibly other path content
- While I do not know when, a sprite viewer, and a more detailed Bio Screen for the characters.
- Revamped Menu, currently it's quite placeholder.
- Splash screen, hopefully a video introduction to P-S.

-I am sure there will be bugs and typos, for all of those, please point them out in the Discord in the appropriate channel. #ciel-cleanup-bug-reports
- As per usual, please do not use older save data, it will likely crash.
- It's a very common bug that characters will incorrectly display upon loading a save. Rollback a view times or keep going and they will correct themselves. One day I'll... figure out how to deal with that.

Illia's Mansion v1.0


Illia's Mansion is an offshoot, somewhat non-canon route for P-S which was never going to see the light of day until... it did. Mika Greenfield, through a very silly non-canon way acquires a board game capable of changing the world around her. She then proceeds to invite her friends and family to play with her and chaos ensues.




An extension to the "mass_possession" path, or specifically five branches of the path. Said five can be completed up until the first day is over. After that, you will be greeted by one of my pending messages.


Other changes are mostly minor and works in progress. Hopefully things to be completed in the next go-around.





A small update which brings back one of the paths (Ashley's Eyes) from v0.3b, with revamped dialogue, visuals and so on.




Version 0.5a is the first in many 0.5 releases planned meant to revamp P-S and put all of the old content back into the game while continuing to add onto the game. Having had to rebuild the game from the ground up, a lot of previous content no longer works properly and has been sealed off. This is the first release, which is merely the alpha release of the game's intitial start, with some minor additions here and there. In time we'll hopefully be able to get everything back into the game and one day P-S will be back whole again and bigger than ever.







The long awaited new content is here in the form of a pathway to take a trip first and truly through all of Eliza's school, a place which was supposed to be a minor location but here it is with more content than the entire rest of the game. In this new path, which stems from an existing one, you take control of Calvin, where he reaches out to Karyn -- his sister's friend -- to see if she would be willing to let him spend a day with his sister inside her all girls' school Olivian High. No amount of forcing would let him in otherwise, and even a switch of his own chromosomes would leave him not on the enlisted girls, so his only course of action is to ask Karyn for the thing which she unconsciously holds most precious: her body.

Experience a path that is unlike every other thing I produced in that it actually functions like an organic path which continually merges back together with itself, with varying options leading to different conclusions much later. The path itself is incomplete. This is part of day 1, in what is planned to be a 3 day path. Day 1 is very introductory, but that doesn't stop it from having it's fair share of missteps, one of which has a very, very, very lengthy ending sequence. Speaking of, endings are no longer numbered, but there are quite a few of them to find. Good luck in doing so~

As this content is not complete, a general rule of thumb is that the path will end upon reaching the end of Eliza's school day, when the final class ends. There are exceptions to this in both ways, as well as a few options which simply can't be accessed due to being cut for either being incomplete, for time, or because I just didn't like them as they were. I apologize for it not being complete as I wanted it to be, but it only makes sense to get it out there now. Something else that is very important to note here is...

This Version Can Only Access The New Content!!!!

If you want to experience P-S as it once was, you will have to download and use version 0.3b. My intention next is to rework the game and get all of the old content working again.

I have an opinion that the author just hates the main character and wants him to suffer... Calvin is presented as a stubborn guy, but in the game he is completely weak-willed and allows everyone around him to use and humiliate him.
Otherwise, one of the few interesting games with very rare updates.

Both iterations of this game are awesome, though I should mention that Illia's Mansion download from mega contained something that WIndows Defender identified as ransomware...it quarantined it immediately, and I was still able to play the game, but a little sketchy either way.


I just hope that Press-Switch fleshes out more paths that focus on the trait changing abilities, like the (very short) chain with breast expansion and reduction. 

In a lot of ways, it reminds me of a less polished, but in a lot of ways more interesting Student Transfer (which I consider to be a huge compliment).

This is just going to be a review on Illia's mansion and not the original visual novel.


The non Canon side story of Illia's mansion is roughly 3 hours of content that is a linear story following the group playing a reality altering boardgames. Due to the kind of things going on, the Visual Novel can get really confusing due to particular things that happen. The visual novel does do its best to try and make things as clear as possible buy if you quit partway through a run the side story again, you might get lost on who is who.


The transformation themes and situations that go on during the game though and really intriguing and I feel the concept of Illia's mansion could have gone even further though for what it is, it is a complete experience and side story that was enjoyable and interesting.

Whew.. Where to begin?


It's difficult for me to sum up my feelings about this game right now, as they've been intertwined with considerably worse feelings for an unrelated matter that was ongoing as I played. But, I have to say, that this game holds a special place in my heart for the levity it brought to an otherwise grim day.


There are a good helping of unfinished paths, which I suspect won't be finished. The one path that is finished however, is lengthy and fleshed out, to the degree of being the equivalent of a finished game on here. There's a full helping of dialogue, both character and plot building, as well as some fun ideas thrown in. If you're like me, you'll feel somewhat annoyed at the forced choices as you go down that path and step into the linear track to the end, but I would say it was worth that. There was plenty of emotion in this story, and though it's not a story I would have written, I'm pleased that someone else did.


If, as I'm sure many are, you're just searching for material and hoping to get on with your day right after, I would recommend searching for another game, and coming back to this one when you have some time on your hands and a hankering for a story. I can hardly qualify this game as pornographic material, and were it not for the occasional nudity I would simply say that it was a 14+ visual novel.


Thank you for creating this game, and I hope that you're willing and able to put the work in to update it further. I would love to see a path related to Mika in a similar way to Ashley, as I always feel awful for the character that's clearly already into the protagonist being left behind. Mika deserves it, she worked hard~
