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.

The patch install involves running a .exe. This was retrieved from the developer, and the Mega link I'm providing is merely a mirror of the archive they provide on their website (click 'Related Items in Free downloads' to get to the adult patch). Regardless, take extra caution as I have not verified this, and I accept even less responibility than the usual 'absolutely none' if there is any issue with this patcher. The save files of the all ages version and adult version aren't compatible - keep them separate to avoid corruption.
