itch.io

you just redownload it and put it in the current folder you have, then you let the computer replace the assets and you're done hope it help

If you have the Itch app then it will patch the game for you (if you're on Windows, Mac or Linux). If you don't have the app, or you're on Android, then you need to download the entire game again each time, I'm afraid.

For Win/Mac/Linux:  Download and extract to a FRESH folder (do NOT overwrite the old files - sometimes I change file structures and it can break things). That's it! The game will automatically transfer your saves over for you.

For Android:  Download the APK and install it on top of the existing APK (do NOT delete the gme at any time or you will permanently lose all your progress!). Same as above, the game will transfer your save files over

Hope that helps! :)
