Really creative, but I think it gets a bit too hard at some levels. I still don't know how I was supposed to "revert the code to older version". I really enjoyed trying to find how to overwrite the AI :)
Thank you for your feedback. To revert the code to older version, you first need to find the code in the div js_loading and then need to uncomment the code after the line
//This was the old code for the AI. It was way to easy.
and then run the reload_code() function in the console!
