We had one Air app, but it got rewritten into Unity (mobile) and is now retired. No, this one is a real Flash app (MMO game), users run it in one of two ways:

- flash plugin bundled into electron, for players with old hardware, ~30% user base

- Flash transpiled into TypeScript transpiled into ES5 JS, with custom runtime based on WebGL

The whole runtime is kinda like Ruffle, but we don't support all Flash capabilities, just what was required to make app running (but it's still a lot of API surface).
