If you are seeing this message, then try loading the page using https instead of http. Or, go to this link: Twins - Remastered

The reason this error is happening is because the library that this game uses to handle sound has a bug where if you launch it without an https connection, then it will throw a fatal error (which can be seen if you open your console). I have no way at all to fix this issue, and the only way to work around it is to load this page using https instead of http. You can manually add an "s" to the URL of this page if you'd like, or you can simply click the link above and it will add it for you. I'm very sorry for the inconvenience!
