Defender's Quest 2(http://www.defendersquest.com/2/) (in development) uses haxe

It's a pretty great experience, I wrote a long post about it here: http://www.gamasutra.com/blogs/LarsDoucet/20140318/213407/Fl...

It focuses on the popular Haxe library OpenFL, but has a lot of information that pertains to Haxe itself as well.
