Looks like this absence has officially been longer than the last one at this point. Hope they come back with an update soon. I know game development is a lot of work and there's always personal things going on as well, so I don't need an update every single day or anything crazy. Maybe just reply to a comment or two once a week to show signs of life or something
Yeah, I follow another game, they post an weekly update every two weeks, on what they've worked on.
They clearly stated that they'll release the update at a certain point and just post like a small dev log.
Something like this would be really good here, because at this point it's getting harder to belive there will even be a next update
Is there still no update after more than a month?
Last game update was more than 3 months ago
That's right, it's been a while since the last substantial update, and I'm optimistic that the next update will have enough new content.
Addressing my absence 2.0
In 4 days, this absence will be the same length as the last one. I know that they said they plan to release the next two updates in the next 5 months, so I wasn't expecting a content drop every week or anything, but at least like some comments or something to let everyone know it isn't abandoned would be nice.
need some help, when i set up a rug both F and R open the fuck machine instead of allowing me to get a laptop
Current version is not playable. Try the previous version 1.5.2-alpha3. Since the dev is playing dead again, only way to get it is on pirate sites.
I've still got plenty of "good things come to those who wait" in me, chief, this ain't nothin'
odin is with us
Good to see the games development is still underway, take your time dont get overwhelmed. If you need help, let the community you built know, we would be glad to help this project come to fruition.
rip game.
how to have sex?
30 days with no update or anything yh he is dead
How do I change my characters sex and idenety?
Hey, why don't we help him finish the game?, we can go through the game by like modding it to finish the sissy part and then the master part no? We would all be working on it and we all won't have any issues
Hey whatever's going on, I hope you're alright.
rest in peace
are you still here?
how loong we got to get woman characters

Did IRL stuff come up? Any info on 1.6.1?
Not sure if this is the ideal way to report bugs but a common one I've encountered is in customizing the bedroom, I can't leave afterwards ToT
Found every time i change places, go to the house to stream or anywhere all clothing and hair on head is removed, completely. so have to go back to appearance to reapply it all. Also if you do the streaming set up it goes right to sex machine setup not streaming.
well, you can, but you'll get a blank void body
Alright, this'll be loosely ordered, so here's some bugs/issues I could find:
Contacts don't seem to actually do anything still, beyond the first request for sex, they won't send any other requests, and their moods won't change.
Some interactions with contacts display empty screens (Send gift, spot me)
During sex, deepthroat seems bugged, I can't switch to it, it just immediately switches back to the previous option.
During sex, the facefuck desire seems bugged, and doesn't seem to get fulfilled.
BJ experience doesn't seem to actually work, at least not with a character made in 1.5
When you complete one objective and immediately end sex you oftentimes get a higher grade than when you complete two objectives
During anal masturbation, it seems to instantly give you a sissygasm after inserting the dildo, and then keep instantly giving new ones
After being promoted to Manager rank at the coffee shop, you still get the option to improve, but the button doesn't work.
And lastly, the advanced goals are still locked despite the tooltip claiming they'd be available with this version
Thank you for the update, even if my timezone doesn't let me enjoy them at reasonable times on release!
thanks. i mentioned a few of them in the post. i'm fixing them right now (including the one mentioned above in your other comment, it's a saving problem actually) and update the game in a few hours, this should fix most of the bugs hopefully.
thanks.
Is the update still coming today?
Glad there is an update. Happy to see it, excitied to see it. However, personal life and fam are more important. Im cool with waiting
Will previous saves be compatible with 1.6?
Hey guys, just wanted to give a quick update. it's around 3am right now, and i'm not home, so i won't be able to get it out at 7am like i planned. i'm aiming for sometime between 6pm and 10pm instead. the update will be out today (february 17, PT time), this is totally unrelated to the game situation, just some personal stuff i need to handle, sorry about that.
Don't stress, dude, everything's cool.
O I thought where was update, went to comments and see this. Main thing is that it is getting released, so yeah its chill. Thanks for informing us. We are waiting.
huh so if anyone was curious this game can be 'modded' to work in vr by using uevr tool, really didn't expect it to work without some fiddling around but it works fine
i've tested few the game runs decently enough using it.
Hope i helped someone in the future
:3
SRS upcoming?
Hello, how is your progress on v1.6.0-a3?
Will it be released soon?
Hello. I'll have a release date and more info on Monday, it's a significant update. It'll be out before february 15th, though. That's all I can really share right now. I was hoping to get it out this month, but I wanna make sure I don't spend another two weeks fixing it. Thanks.
Thank you. We will wait.
Valentines days present LMAO
Can you give any news about new things?
I know there is a lot of work and small details are not a priority, but I would like to see in the next update the traces of cum in the mouth, etc., like in the beta... it arousing
After playing the latest release, I have still noticed an issue with goals. For example, If I have previously purchased a regular chastity cage, and then start the goal, it doesn't register me as already purchasing it, and will not let me continue.
The game should check ownership instead of purchasing.
And for the "wear a normal chastity" goal, the game should check ANY cage because if you are kidnapped before validating this goal your are locked into another cage and don't own the key.
Hey everyone, I just bought the game and had a quick question.
Is anyone else missing sound?
Also, is it intended that the graphics look a bit worse than in the demo?
Hello.
Thanks.
Thanks for the reply! The game is seriously great, even in alpha. Thanks a ton for all the hard work you're putting into it. I'm excited to watch it get even better!
Man, i have 1 question: when u publish a
v2.0.0-alpha3
I really want see this version )))
I think they're gonna hold off on giving release dates for future updates so they don't create any frustration in case of delays, which I think is a great decision. I'm definitely excited for future updates too!
if you dont mind me tellin you another bug in master mode that money remain the same u cant get more money or less it remain 3k, and u cant obtain new contact after the first time u get them. Also if u can please fix the light in the dungeon its just too dark u cant see their face during BJ. Thank you so much for your hard work and appreciate your time making this game as amazing as it is. Sorry frogot about the DPT endurance doesnt level up. :)
Can you open a business on master mode?
Not yet implemented. Sissy mode will be complete first, then work will begin on master.
I forgot how does the master path has sex with a slave?
+1 but also i forgot how you can you go to a hotel with a contact and fuck him
it's a bug. master mode is buggier than usual right now. i did put a warning about it in the game. sorry about that.
edit: it seems like sex in the dungeon is working, but the motel meeting is bugged.
