Is there API to get game usage statistics, make high score list and user feedback on your site?
Hi @enot (привет).
At the moment we do not support any leaderboard or user data storage features.
But there are many existing solutions that you easily can integrate in your project, such as:
Facebook Scores API - https://developers.facebook.com/docs/games/scores/
Google Leaderboards - https://developers.google.com/games/services/common/concepts/leaderboards
And there are many more services that provide such functionality, most of them do support all platforms including JavaScript web based games.
