The whole Haxe ecosystem flies under most people's radar, partly because it evolved from what was once the Flash ecosystem. It never really qualified for the kind of "NEW SHINY THING" announcement that creates hype elsewhere. A lot of people who have written loads of games are peripherally aware of it but have never actually gotten hands-on with it.
I've said before, I about fell out of my chair the first time I looked at the games created with Heaps: Dead Cells and a few other top tier indie games I had been looking at. Still haven't gotten around to learning Haxe though, hopefully soon.
