I use Haxe and really enjoy it. I use it to develop an MMORPG ( https://jamcloud95.com ). I've remember going through quite a few different game engines (Godot, Unity, Defold, etc.) but HaxeFlixel had the most "natural" feel for me to code in, which is largely due to Haxe itself.
Can't enter any letters into the codename/pass/email prompts under android chrome, so can't get passed email prompt. Probably not the right place for bug reports though.
I'll take bug reports anywhere I can get them. I'll see if I can reproduce it—and thanks for the heads up! A dedicated Android version is also on the way.
