itch.io

Pretty sure if you download and install the newer version itll update the version youre on. Im not entirely sure though.

Just download the new version and extract it somewhere else, not on top of the old install.

Run it, make sure your saves are there and then delete the old version.

On Android, don’t uninstall, download the new version’s APK and install as update. You can delete the apk file afterwards.

Also, on computer you can use the itch.io launcher to keep the game up to date.

If you use the Itch launcher, it updates automatically. Most Renpy games store their save data in a specific place, so it should keep your saves regardless.
