(THIS COMMENT HAS BEEN EDITED TO INCLUDE A NEW VERSION OF THE TRANSLATION)
Hello! For those looking for an English translation here's my unofficial one:
https://drive.google.com/file/d/1B5HZVLH-Wq575ST8f3UyyfmR78ergjfd/view
If you've installed previous versions of the translation - or if this is your first time installing it - listen up! The install has slightly changed.
Move the contents of the "www.zip" into the www folder inside the game, e.g "恶堕之旅-2.0.8-windows\www", It should prompt you to "replace files", choose to replace them all, and that's all!
Example of what you should see when installing.
