The fact it's using C++, which makes things like object-oriented programming very easy with little or no overhead (i'm not sure about this). Because of its ease in use I've started writing more haxe/hxml than cpp! It really has helped me understand how OOP works at such low level because everything can be done through functions instead classes etc.. And also for some reason when i don't think my flash player version will support hxsl compiler error comes out even if there are errors inside your program logic!?! No idea why but maybe something wrong while creating packages? So far so good though :) Try as hard possible :P If anyone have any problem during development just ask here ;) You'll find answers quickly enough ;p Also try other flixes too they're all great projects worth checking.
