There IS an uncensor patch available for Fallen ~Makina and the City of Ruins~!
The patch HAS NOT been verified - proceed with caution.
Verifying patches means owning the games, which while I would love to own every lewd Steam game, is not practical for me at the moment.
If you have an interest in helping me out with game access, get in touch through the contact page!
The patch install involves running a .exe file. This is directly from the developer, and the Mega link I'm providing is the same they do on the Kagura Games website (along with some images detailing the install process!). Regardless, take extra caution as I have not verified this, and I accept even less responibility than usual if there is any issue with this patcher!
Download the patcher from the link below
Extract the patch installer from the archive it comes downloaded in
Run the patch installer
Read the agreement and if you accept the terms, click "I Agree"
The installer should find your installation directory automatically, however if you have installed the game outside of the default directory location, you will have to point it to your game install location
