Great! I can't wait for android support, I don't have the HTML5 module quite yet. Are you also planning on making a C++ .dll for desktop cross-play also?
P.S. When you add more features/out of beta you should increase your price to probably $35 or $40 at least. GMS is kinda weak with multiplayer and the best solutions cost $40, $99, and $150 - and gamesparks can target all platforms where the best these others do is 1 or 2 platforms per extension. Hope I don't end up screwing myself but I think you are def undervaluing your work. :)
