Thank you for your concern! Just letting you know, due to the nature of the way the game is created and coded, even if the other official host and the multiple (unofficial) websites hosting a copy of the game went down, we'd still have the development site, and even if THAT went down, due to the nature of the way the game is created, with multiple Contributors working on various sections, the raw game code exists on multiple computers at once. There's essentially many backups being created all the time!
If itch ever does decide to go full weirdo and remove all adult games, regardless of content, there's already been discussion of having a SFW edit here and the full game still accessable on the Homepage, which you can visit under "More Information" above!
