Looks good! Thanks for the quick fix.

I observed that website does not have a name either. But it seems to be fine, because the error message says: Package name "undefined" used in multiple packages , so it's fine to have one undefined, but not having two 😆 .

Yes, let's take a look at that separately. I don't want to mess up that package. The puzzle package still isn't in use so there won't be any harm in adding it.
