Well, that was actually a bit tricky to get my head around at first.
I took the liberty to check out some other entries after I got stuck a bit, however after that I got to have fun with it and decided that my game should be a little sarcastic.
Additionally, It seems that error messages not always disappear instantly. Does anyone else experience this as well? (tried to replicate the error, but did not get it to return)
For the record I know “hello” is not an isogram. 
Loving this course so far!
