that does look interesting. so this would mean we work through AWS? It seems like a whole other angle to Construct could be opened up if this were possible. Even using something like Paypal perhaps would also work? Whatever is easiest, but yea that would be pretty awesome to have. I wish there was something like parse for storing / saving data. I know it's generally "deep" to do online stuff but still fun to imagine it being possible.
Afaik it doesn't have anything to do with Aws, other than they are using Amazon servers to handle requests.
This seems to be just iap. You would use local storage, or some third party plugs for Parse, or Firebase, for storage.
I would add that Amazon is launching a leader board type service called GameOn, which seems to be platform agnostic.
