I downloaded the 3 savefiles you uploaded and moved it to the game's "saves" folder but whenever i tried to open the updated version, an error screen pops up and i am forced to restart the game everytime i click the "ignore"
You downloaded the latest version of Heroes University H 0.0.2.4.1 right? You could try dropping the save files in the %USERPROFILE%\AppData\Roaming\RenPy\Heroes University H 0.0.2\ path as well, and note that the save files correspond to the first 3 upload slots.
Yes. I downloaded the updated one (0.0.2.4.1) and the last version i have here is 0.0.2.1 and i'm using an android phone so does the save files only work for PC users?
Save files also work on Android. Sorry, I don't quite understand what you mean, how come you downloaded the latest version (0.0.2.4.1) but you have 0.0.2.1? Anyway try uninstalling any version you have installed on your phone and install version 0.0.2.4.1.
Done. Sorry but it's still the same. The only one i have here now is the latest version and i moved the save files (which i downloaded again) to the game's "saves" folder and it still shows the error screen from last time. The "saves" folder seems to be the applicable folder for the save files
