Its really exciting to see this work. My own knowledge of Haxe is minimal so I can’t be as helpful as I would like to be, but if there are other HaXe developers out there, your help in the effort would be really appreciated. The conversation around the port is happening at the OpenPyro mailing list.
In other news, OpenPyro finally has an official home at OpenPyro.org. I am going to start posting architecture documents and examples there. The latest can be found at the OpenPyro wiki and the OpenPyro asdocs page.
