If you develop a mobile game then a save game feature to backup your progress online so user can change devices without starting over again is a vital key in keeping customer retention.
Now we have three major options to do this:
Google Play Save Game Feature
I have seen request posts for Google Save Game as most indie mobile developer's first focus is google play due to its affordability and popularity, but "its not beneficiary for all as is platform specific" - according to scirra.
So next best option is Firebase which can save for all platforms the database to hold leaderboards and game progress, But there is no plugin support for it in construct, there are many request posts (as majority of construct users are here for its non-coding platform i assume) for many years but its not yet implemented i don't know why.
Now the next and possibly last viable option for construct users is to use MySQL with free web hosting sites, but the problem is that noone wants to put login id and password anymore (in games atleast) as most of the games out there use a simple one click gmail login where user just have to choose the email id and its done. (Ex : Subway Surfers)
And if i am not wrong, this is also not yet supported by construct. So my question is when? as it could be the most basic feature that can be used to get users to save progress with ease.
