Hello,
you might not read this because it's been weeks since you've started this thread. I want to add that OpenFL added support for TypeScript and JavaScript (ES5 and ES6) a few months ago:

What is OpenFL? It's a framework that is also being used by HaxeFlixel. JavaSCript and TypeScript might or might not limit your OpenFL games to HTML5, I don't know honestly.

Best of luck!

@gama11 Thank you! I hope it wasn't too much work for everyone involved.

Thank you very much.

Just to let admins know in case they are unaware.

Cheers.

The art is fantastic. Can't speak for the game because obviously it hasn't been released yet. Please keep us updated!

Ok, I just needed more patience. It's working now.

Neat graphics, but can't seem to get it to work for some reason.

Congratulations! Will you post a trailer, too?
