We just released our second game in Haxe on iOS a few weeks ago and we're releasing the Android version in another 6 weeks. It's a Unity client with haxe-generated C# code and then javascript and node on the server. There have definitely been a bunch of hiccups and hitches along the way, but it's been pretty good overall.
