Am i an idiot? because i can't seem to progress past the breast expansion and the mind control one.
Edited: Nevermind i guess i found out now
Thank you for the butt expansion content. Much appreciate!
very god game, waiting for updates here
I hope this game gets an Android release
Great game! I love the art and the writing, I think this has a lot of potential. I'll be looking forward to updates. But, I do have a couple "complaints", although they're more "things that I noticed that could be improved to make this game even better."
I noticed an inconsistency with the cup sizes in the breast expansion sections. On the lvl 2 dialogues, it says "increasing from E to G", but on the final stage, it still says "increasing from E to G". If the intention is that this process of increasing from E to G is happening across these two transformations, it could definitely be communicated better.
Also, I'm a bit disappointed that the hard nipples didn't persist outside of the initial transformation event. I like nipple pokies a lot, and even outside of that, it'd make sense for them to show up again maybe during the regular talk dialogue when she moans, and definitely during the first part of the final breast expansion scene where she actively talks about how good her nipples feel. And it doesn't seem like it'd necessitate making new poses, either. (Admittedly, I haven't gone into the bimbo TF path yet, and maybe that has more nipple pokies, but if not, I think they should also happen in the base biggest size boobs poses.)
Anyway, yeah. I'm definitely eager to see what sort of TF you have planned for next update!
thank you for the feedback!!
i didn't notice that I indeed repeated the same cup sizes twice, so i'll fix that next update
also, the bimbo does have a sluttier outfit + nipple (and piercing) pokies, so hopefully you'll enjoy it too!!
Yep, I did see that, and I definitely enjoy the bimbo TF. I still do think that the one section in the final BE scene should have erect nipples, though.
Any chances of a phone compatible version coming out anytime soon?
Is there any plans for AE perchance?
I'd love to see that too! And it seems like it will be in the game, judging by the intro.
What about android?
the pronoun selection dont seem to work
I might have missed some pronouns somewhere, since i had to go back and change it by hand.
Can you please let me know in which scene, or which line isnt changing?
right at the start the protag says "im a guY" for one thing
Ah shit. I mainly searched for he/him pronouns to replace, so i didn't notice that.
I'll fix that on the next update, thank you for reporting!
hope you can also change the art for MC to reflect gender at some point i get right now this is still very early in development just would be neat if the story reflected your pronouns in the art
Hi again! i figured out the problem and it was super silly, because of a pc update my software was labeling the file as unsafe because it was from a unknown publisher. Super great game!
any plans to continue the BE path further?
It is planned to both add more scenes and content to the current BE path, as well as in the future continue this path with hyper BE!!
Is there a way to mod this game to change the girl's name? I have a close relative named Mia and this game would otherwise be up my ally if not for the ickyness I feel from this character (through no fault of the dev) sharing the same name of a blood relative.
When starting a new game you can change both your name and Mia's name!
Fucking sweet!
Only Just started, but loving it so far. Honestly I love how into it Mia is as well, it really adds to the fun for me!
Hey, just curious do see if there will ever be a version for this on Android, looks fun and I'd happily throw some cash to get it.
HELLO HAIIII WANTED TO KNOW IF YOU HAD ANYWAY TO PRIVATELY MESSAGE YOU REGARDING THE GAME? had a very special idea that you might want to hear! anyway please let me know or just look me up on twitter to pop me a message! (would have messaged any other way but couldnt find your twitter if you have one and I cant message you unless i sub which uhhhh im broke)
i normally only use bluesky (@tightly-dev)
but I have a twitter that I don't normally use, feel free to DM me there if you want!! - @tightly_dev
loved every second. i just wanna throw out two suggestions: hourglass expansion and shortstack.
I absolutely LOVE the amount of hypnosis in this game, its amazingly done, and i yearn for this type of hypno content, sad to have finished it all so far in the free version, What an amazing concept !!! I hope for more hypno stuff in the future!!!
Will you ever make an android version?
OMG I LOOOOOVE the opening segment xD Came for the porn gonna stay for the humor x3
Possible android version? ( ͡° ͜ʖ ͡°)
Been loving what I played so far keep up the good work
I would love to give myself big tits just so i can make money from only fans. as a man with a very small penis, i have to compensate.
im on windows how do i get it to work when i download it?
I loved the butt expansion section, awesome stuff! This game is really shaping up (pun intended) to be a great experience. Thanks for your work!
love it, and your humor is great too
but will she forget everything that happens each time you reset or will that change in future updates?
i mean, if the reset doesn't make her forget...
That would mean she's just putting up an act for role-play purposes?
Hmmm.... Surely Mia would never do such a thing~~
So we won't be seeing any progress in their relationship?
maybe i should have put a /s in my last sentence.
yes there are plans for the relationship to progress in the future.
for example, we'll see a difference in dialog when changing from hypnosis to boob enlargement?
hope the sizes like double are triple in the future.
however, I cannot start the game when I download it
sorry to hear that.
have you tried starting the game with "CompatibilityLauncher.bat"?
if that still doesn't work, please do the following steps:
Then inside it type: .\ModificationApp.exe
Let me know what shows up in the terminal when the game crashes
ngl i am not very tech savy and I'm too unintelligent for this. However, my opinion still stands when i first played the game when it came out, it was amazing, and i bet it still is im just too dumb, maybe tomorrow i will get a friend to help me run this. thanks for your time!
Don't install rn I tried twice and microsoft blocked the install due to the files containing the trojan virus. luckily microsoft defender blocked both installs.
update: tried installing and scanned the files to look for the trojan its no longer there.
PEAK!!!! Minigames are nice, too!~
Waiting for mind control expansion~~ (even more surprising cuz im not a fan of hypno app tropes). Tho i hope it'll be more like what's bimbo trope is doing, not just slight body control (like mind control → brainwashing or something)
P.s.: btw can you tell me whats the song is used in arousal moments? Istg i've heard it somewhere but i cant recall the game
P.p.s.: also i think if you're gonna make new paths as you've said (in the middle of other paths) it would make sense to make an option to return to previous or different unlocked stages through "paths" app instead of re-doing the whole thing every time something is added.
I must be missing something, but after bimboficatio lvl2, I seem to not be able to progress further. I have skipped multiple days, but she has not returned home. It also seems like there are more paths after bimbofication lvl2.
Also, how can I do the mind control path, other then after/during the tutorial?
after bimbofication lvl 2, you should have a tip on the app of what to do next.
but basically, you need to go to your living room in the afternoon. You should have an option "play videogames" with a star next to it.
for the mind control path, it's started on the living room in the afternoon in the default state.
You can use the Paths app on the phone to see all the paths that you've unlocked (and where are the ones you have yet to unlock)
so the mind control is started in the living room and the breast expansion in the kitchen?
I got a tip that said something like “tomorrow is a new day”. I’ll restart and try again. Thanks!
I just finished the bimbo branch. No idea how I missed that prompt.
Please make a mobile version of the game if possible
very good update and good update schedule you must work hard
One of the better nsfw games I've played here, pretty well made too. Keep on keeping on, I can see this getting a lot better in the future!
dropped a follow cant wait to see more!
also noticed a lot of recommendations didn't want to dump mine into the already flooded mix!
holy shit, pronouns option ??? Which means you're not forced to be male ?? Retweet to scare 90% of nsfw gamedev
mabye make it if i click on somthing in the path tree it changes her into that so if you add onto a path i dont need to go though it all again
Any plans for a Android version (please i have no pc nor anything with MacOS😢)
