Believe it or not, this game is slightly modular.
Packages can be installed in some versions of the game to add additional fruits and/or characters.
Anyone can create a package, compress it to a ".gianniapppkg" file and distribute it to others to add to their game installations.
All data generated by additional fruits & characters can be synced between devices with gianniSync.
NB: only the data (eg. amount of eaten fruits, purchased fruits) is synced, not the packages themselves.
There currently isn't an official package directory on this site.
However, there is a list of official packages.
