If you have any news let me know, in game it still works but I can't seem to manage it, but I will try to create another one to replace it now.
Due to a new browser policy copying to clipboard became broken on some browsers and I am working on fixing it. As a temporary workaround, I made the keys appear on top of the Unity view, so you will be able to copy the keys from there for now. The keys are alternatively printed in the developer console, so you can copy them from there.
