If you are in the Indie & Student Programme, pricing for your games in development and live games are not affected. You can continue to use GameSparks for free up to 100,000 MAU. Support is limited to documentation, forums and tutorials, and the updated Usage Limits replace the old Fair Usage Policy.

As I see,  official support in forums is basically nonexistent . If I keep developing, go live and encounter a problem related to Gamesparks especially at the first stage where the app is not profitable, all I can do is hope to fix it by themselves.
