How does one switch the language to English?
I downloaded translation
where is that?
where?
What you do is:
You open up the folder and go into “BepInEx” folder.
Then into config. You should see three files.
Open “AutoTranslatorConfig.ini”. It should open Notepad, go to “[General]”. It should look like:
“[General]
Language=
FromLanguage=ja”
All you must do is add “en” after “Language=”. It should look like this:
“[General]
Language=en
FromLanguage=ja”
This is a scuffed-to-literal Google Translate, but at least you can understand it.
Gonna bump the question, “How does one switch to the language to English”, that Reveren posted.
I found the EN file within the install but all three text files were/are blank.
theres an error everytime i try to extract it. is there something i can do to fix it?
Try extracting with 7zip.
how to download and apply uncensor patch
Download the uncensored patch from fileknot link.
extract and replace files into your game _Data folder
Could you update the game to the ver2023.02.3?
It’s not available yet.
When trying to download my virus scanner states this is a Trojan Virus.
Is there any good game like this one ?
Not bad, pretty good. I just wish there was like a New Game+ or something that lets you continue past 1 month.
Found a bug: Choosing upgare after clear the game, you can’t decrease your HP but if you +1 then -10 you can bring down your HP to 0
