This first version of the Kartridge SDK has three primary capabilities: getting user information (including authentication), submitting stats that we can use to put achievements on your game and allowing access to in-app purchases.
We have C++ and Unity/.NET (C#) implementations with Game Maker and Adobe AIR versions in the works. We don’t yet have tutorial or README docs, though they are coming soon as well.
