I’ve never implemented the Kreds API. I am currently working on a title that uses microtransactions. If your game is successful and mtx (short name for microtransactions) does well, then it certainly will be worth it. ;)
QuickKong is geared to be neutral to all APIs. It is just as easy to use one as another. If you enable microtransactions for your game, you can access any part of that API through
foobar() is an api call, after connecting to the API early in your game.
