The link below was retrieved directly from the developer PixelGreeds on the PixelGreedsGames Discord server. While this patch involves running an executable file, it is merely a self-extracting archive, the contents of which is a single file "package.nw" containing the uncensored art. If you're concerned about running the file, opening the .exe with WinRAR and extracting the file directly into the game install folder should work just as well.
The current patch linked here is designed for version 1.0.4 of the game. If there are any issues with this link, please let me know on the Contact page.
The developer also recommends turning off Steam Cloud updates in the "Updates" tab of the game options in Steam.
