"You'll need to download an NSFW patch here on Itch to turn Monstergirl Hunters into Ero Hunters. Patching works the same as hotfixing, i.e., just place the .pck file next to the .exe file." -Mado, first paragraph of this page
Monstergirl Hunters will be hosted on Steam. The patch to make it Ero Hunters will be hosted on itch.
