If you use an llm, it can properly quickly reformat your game into the json formatting of kinexus - by simply copy/pasting your game code into the llm and the copy/paste the format json descriptions on the github page into the llm, and ask it to do the reformatting. Hit Ctrl+Alt+D for starting debug mode in Kinexus, before importing the json. If there are import errors you can see them there, copy/paste the log into the llm and get it to correct the json. I'm using https://aistudio.google.com/ (plenty of free tokens) because it's got a huge context window - but you must tell it to reply with the complete and fully working script or it might try to shorten it.
