not yet, but there was a new update about the game in the dev patreon, for now, they haven't dropped the game, we can expect new content soon

Really wish I could play it, can't really find out how to save the game, I've read everything I can find about the saves, I just can't find any file it downloads so that I can rename it and put it into the same directory (I assume this has something to do with flash not being available anymore but I don't get how other people are able to play it then).
