Include a query string in the call to the script, and you should be able to bypass the CloudFlare cache.
The problem is that you cannot do that with Jocly. You can do it on the page it is embedded in, for sure, but when you start it, it will load all kind of JavaScript and image file in the background, the name of those files often read from other json files, where it derives the filname by manipulation of strings in JavaScript. (E.g. concatenating the game name with some postfix.) It is an incredibly complex mess, and Jocly won't append a query string to any of it.
