In that email for 13.5, you also get access to future versions like 14.2, if that's not the case please contact me by email at redikalsoftware@gmail.com
Hello, I think there will be more updates although there is no 100% guarantee, because last time we heard from itch.io they were working on a solution, so the moment they deliver, we will be back.
You need to chill a bit okay, this a demo version of the game, I'm not doing every day support on it, inside the game all the links are available to reach Steam/Patreon/Twitter. It's not because there is no reply for 2 weeks here that the game has been abandonned.
It's most likely a non official version, official doesn't have problems or if you have the official links, then redownload apk, this has been fixed sometimes ago.
There is no full game at the moment, it's being developped, you can get the latest version on Patreon if you don't want to wait, otherwise it will be available on Steam and here as soon as nsfw games are reinstated.
Check if your phone allows installing apps from unknown sources. If that’s already on, uninstall the old version completely, restart your phone, and try installing again. Otherwise don't know.
