There are other flash "replacements", the one I like the most being Haxe [0] (transpiler to flash bytecode, javascript, and more) + OpenFL [1].<p>OpenFL replicates flash API [2], can work with Adobe Animate (formerly flash), and can use swf assets [3]. There are also converters from AS3 to Haxe, both available and not yet released (like the one used to migrate Forge of Empires [4]).<p>Haxe + OpenFL can export to flash player, HTML5 but also to native (desktop, mobile, consoles).<p>[0]: <a href="https://haxe.org" rel="nofollow">https://haxe.org</a>
