It's obviously a problem because it doesn't work as intended/at all. What's point of building something like this if it doesn't work? At best its a waste of everyone's time, at worst it's misleading.

It's not fun because it isn't challenging. I have an expert-1 level of English as a native speaker and heavy reader. But absolutely nothing in this is challenging at all. The one question I got wrong was because the 4 proscribed answer options weren't specific enough. So overall there's no value in this.
