Okay, I actually played it this time, and the controls are a bit more confusing than I expected for such a simple game: I feel mouse controls would make much more sense than using 'W' and 'S' and 'Enter'. There's also little that motivates me to keep going after messing up an answer, given you're forced to start over with a single mistake. And finally, the questions feel like I'm expected to have a search engine open at all times to look up their dates.
