@Castari
While I myself don't have sufficient programing language in the area of graphic engines development I won't be able to help you out directly.
But since I was planning on using Asphyre Sphinx for my games I would be folowing your further development closely.
Also you can count me in as a bughunter if needed even thou I'm currently only limited to Windows platform. I do own Delphi XE4 myself.
