Just got back from the haxe conference, wwx2014, after having a great time. Plenty of fantastic people to talk to.
The talk consists of some slides, with a demo at the end. To run the demo, you need to run the binary version on either mac or windows, but the slides can be viewed with flash.
Or, you can build it yourself for you preferred platform and explore the source code with:
haxelib install nme haxelib install gm2d haxelib run nme demo gm2d 10-wwx2014 cpp
Edit – must mention that you might need an dev version of haxe to build the demo.
