I started evaluating Cocossharp back in April and finally finished my first game, you can check it out here https://play.google.com/store/apps/details?id=uk.co.procog.HairFlee.Droid. Generally, it has gone pretty well but the game is relatively simple and before I start my next effort I'm going to consider other options. The big plus for me with cocossharp is c# and I'm sure I'm not alone in that, it would be great if it was more actively supported and developed. Has anyone heard anything about Xamarins' own plans?
