I'm using HaxePunk and feel satisfied about it, except one little thing.
How can I use achievements, in-game purchasements fro, google play? Is there any lib for OpenFL or HaxePunk?
I've found only a lib on github, but seems like it is only for Flixel (not HaxePunk) and supports only IOS: https://github.com/prestia/hxgk-flixel
If there is no lib actually, what should I do?
There are the openfl premium libs with support Gamecenter/Play and in-app purchasements http://www.openfl.org/marketplace/premium/
