Is there a different place where I could download the r18 version? My phone is weird and doesnt allow me to download games from itch.io.
If you're looking for the *mobile* version of the R18 version, this is the only place you can get it. It's incredibly rare to find places where you can upload R18 mobile games. From what I know, Itch.io is the only credible one currently.
The PG-13 version of the mobile version is available via Google Play.
If you just want an alternate place to download the game in general, it's on Steam. (Steam does not have mobile games though.)
