Can we possibly get the APK download hosted on a diffrent site? Only asking because the ingame update launcher clearly is causing more issues than it is fixing.
Hey, it's not a problem of the host, the launcher is the only way to get the apk version working at the moment. If used correctly, it shouldn't cause any problems, unless there are server-side errors, which cannot be predicted and are handled by external people.
On android and the new update has no Neon images. I can't test anyone else because I have to sleep to do anything new and that means I have to go through Neon's scenes.
Have you tried downloading the update again?
Do I have to uninstall the whole thing or is there a way to reinstall the update only?
That worked. Thanks.
"Its times to see what's beyond the portal, get out of your office jin."
I have no idea what to do here and would love to know what to do. Thanks
Continue the main story. Then try looking for Jin again. Try different times of day aswell.
Thanks mate, figured it out
My launcher keep crash after the update,what should i do?
Try again, the server was down.
Cant progress Hidden Links. Whenever I go to the strange structure theres no one there and my character just remarks about the sign saying they were open.
Edit: For anyone else who is stuck here, I figured it out. Need to finish beastly meeting first.
When i choose the "be my alarm clock" option this error happens, and after pressing "ignore" it takes me to the "gift" option
I've got errors coming out the ass and getting tons of "image not found" messages.
Man the in game launcher download doesn't move after 5.7% and yes I tried downloading waiting but it did not help I even deleted the game 3 times
Some of the scenes still popping up as image not found for a lot of the characters this is the 4th time I try to restart everything
Same here. Additionally the etheria timer is permanently stuck at 7 days remaining.
Man for real. Please don't tell me this is an AI Revolution situation , as far as I know the devs still haven't fixed it over 2 months later and as far as I know no word is out on if they are even going to fix it.
Everything is working correctly, it has been tested several times, the servers were down due to a problem, but now it should be working. If not, please download the update again.
Sweet! Still haven't even gotten word from AI Revolution dev
Downloading is fucking slow i waited 1 and a half hour an still not finish
That’s an issue between you and itch.io. Individual game authors have no control over that, especially when their files are hosted on itch.io.
This game was so good too, one of the only downsides to this game is you have to play every character to play others. I knew from the moment I met Syxia I wasnt gonna like her and the minute she shoved a vile down my throat I instantly closed the game. 7/10 the stories great actually I just dont like being forced to do quests for characters I dont like.
I can't collect more etheria, it says 7 days until i can collect more but it won't update so I'm stuck
The screen is locked into the timer?
Yes, the timer isn't progressing
I think he means that the timer never progresses. I also have this issue.
It got fixed, check the update.
Me sale este error cada que cargo una partida después de actualizar, ¿Hay alguna solución?
press ignorar
Im trying to update from inside the game but it's so slow even with a full speed WiFi is there anyway that can be fixed?when I was downloading the rpa from site before it was fast but it's incredibly slow in game
On the Discord they mentioned there was a server issue with the launcher. It should be fixed now
Help i downloaded the app on Android and this start showing up.can someone know how to fix this?
The same thing is happening to me I was coming to see if there was a newer update or fix.
Same thing is happening to me
Hey, How do continue with Isabelles storyline? I have a hint that says ''Unlock first neon''... what am i supposed to do? I'm confused. Also how do i give the girls their rooms? There are not any that i could find.
For Neon progress more main story, the rooms instead first you have to repair them with Taile.
I was curious why the active quest line is in Spanish but everything else is in English. Is there a way to change it back to English?
That's strange, did you change any settings? Check the language menu.
Uh y is the apk version all images error
The servers were offline, try now.
Still getting image errors here. And the etheria timer doesn't work. Or rather, it prevents etheria from respawning entirely. Everyday it says 7 days remaining.
Where is the content in the update I update the game and it still shows 101 not 102 I even deleted it and re-downloaded it still version 0.101 this is the second time maybe when u say there's an update make sure the update is actually ready to go cause u just giving people false hope and make them wait longer for the actual update L creator so far u are not doing good on these updates 2nd time the game won't update when u say there's an update
The android servers were offline, so the launcher was downloading nothing, try again.
Thanks it worked but the new update has been having some errors
why is this game not showing up on feed?
Why is literally 90% of the game just missing for me? No scenes are visible, not even story images are there... I can only see the text but nothing else
i have the reverse problem my text is now just tots like save is " . "
can i play on windows 7
how do I convince Sheila to join new house and then complete quest the call?
Now I might be missing something but I updated the game and uhh nothing updated? Like literally I got no new event as described in the change log. I'm on Android so idk if the APK is just being weird or something.
Edit: I just checked even tho I updated the game still reads version 0.100 and not 0.101 welp
Edit 2: after some shenanigans I somehow made it work by almost losing all progress and deleting the game. Now I saw some issues like when one of the characters asks you to go with them out in the morning, their scenes get replaced by another character. I don't know if that is an issue with the download or the build itself.
How did you get it to update cause I'm having the same issue.
So I installed an app manager called files (by Marc apps & software, idk if it is 100% safe it is on Google play tho) and I copied all save files in another folder. Then I deleted the game, installed the new launcher and proceeded to install the game again. after that I recopied the files in. If you can't use the app for some reasons you should be able to plug your phone on a pc and copy the files from the pc as it has no restrictions
most likely a virus or malware use malwarebytes to make sure ur pc isn't being hacker or any malware on your computer it's also pretty good at detecting them but not all the time you can also use it to scan the file for anything but do be careful what you download from my experience. You can also use windows and R and type in NETPLWIZ to make sure nobody else has access to your computer or control if you see someone else remove them asap because if someone else is logged in they can steal info and other stuff.
It's a Ren'Py error dude, it's not likely a virus at all.
ah okay
love the game but its extremely buggy on windows 10 a few h scenes were missing from hera, the core kept crashing my game, a few menus like what interactive scene i could choose with the girls or change their clothes got stuck and had to reload a past save, one time i did a "work the bar" and it ended up making me work for tal which moved me to dusk city, i was doing the living room scene with mikosh and a few characters got stuck up on screen covering her, clothes didn't work i couldn't put them on and if i tried it freaked out and only gave me the option to hug the girl but the screen would get stuck, one scene with tsukiko looks very unnerving like she's got the body of golem from LoTR and lastly i went to go to bed and the game crashed making me lose a lot of progress i really enjoy the game an amazing story and animation i hope the majority of bugs get patched in the next update
Well a lot of things were refactored recently thus there are unforeseen bugs (not only on Win10) and a lot of them have been reported and fixed, but feel free to report if some remains as the team cannot fix those if nobody report them. And a friendly advice, save frequently, Ren'Py allows for literally hundreds of saves.
