Also The Steam "version" is the same Flash game and Steam acts as a browser and uses the Chrome PPAPI Flash plugin (at least in Linux it requires 32-bit Chrome to be installed)
On July most of the browsers blocked Flash because it had a 0-day vulnerability but was re-enabled when it was fixed.
"Independent Client" would mean at least triple the work compared to Flash to make the game available to all the current players (Linux, Mac and Windows). HTML5 would be the only viable choice if Flash couldn't be used any more.
