i have a question, if i downloaded the new version my progress will get transferred right? Then if i deleted the old version would my progress get deleted too?
I don't know with another version. But in PC Version you can copy file "saves" in file "game" and paste "saves" file into your new "game" file to make sure you won't losing your game progress.
FYI Game which made by Ren'py engine usually automatic generate backup saves and persistent file in %appdata%>renpy so please don't worry about losing your game progress.
