I think it used to be flash based online so when Adobe murked the ole player on browsers Changer would have no reason to keep it up.
Adobe did end support for Flash but that was back in January. New versions of the game were still getting uploaded to play from here until just a few days ago. Some of us were still playing it with certain browsers or players. Why stop now unless there was some other recent administrative change? Maybe eventually new versions can be uploaded in another format like HTML.
