I use C2 Cocoon Google Play Games plugin in my games.
If you look at the cordova plugin code, it seems that it supports cloud saving, but this is not supported in the C2 plugin. I need someone who can modify the plugin for C2 to support this feature.
Here's what need to do:
1. Add the 'drive.appfolder' scope to initialization method
2. Add methods: showSavedGames, loadSavedGame, writeSavedGame
