I'd suggest not forcing a signup to use the game. People just don't have the time to signup <i>again</i> for a game they don't even know if it's worth it.
This is so much fun!<p>It would be great to know how many people are currently online. I played three matches, each time against the same person - who I presume was selected randomly, so there can't have been that many people playing.<p>Also, does it automatically disconnect your opponent? I'd often like to demand a rematch, but every time it says "JSmith has disappeared!" - I don't know if that's because all my opponents hate me but there should be an option for a direct rematch.<p>Finally, I found sometimes the countdown timer when an opponent can still answer flickers randomly between actual time left and around 12-15 seconds. It's hard to describe but there's definitely something wrong there.
You should override the default behavior of Backspace, because if someone is not in the input field, Backspace will abort the quiz and take them back to the previous page (in most browsers).<p>Maybe the multiple choice option should only become available after a certain amount of time?<p>I would decrease the time a user has to fill in an answer. Where there is competition there is generally cheating (who would do that right? I know), and you want to prevent GoogleIntellectuals from doing just that.
Very fun. I have only one gripe and that is the fact that you have an alert pop up when I try to leave the page. I hate alert messages.
Other than that the game is really fun and the questions are difficult enough that I don't think googling would give me much of an edge given the time restriction of each question. Good job.
Long questions with long answers (What is a situation called in which the inflation rate is high and the economic growth rate is low? - stagflation) require more time than short questions with short answers (What herb is used in a Mojito? - mint). I know the answer to both, but I only got the points for one...
Please don't require using another service to log in. I hit "Sign in", saw the Google, Twitter, and Facebook buttons, and immediately looked for the "no, I really want to use a username and password" option.<p>Also, the Twitter authorization requests permission to read tweets and followers; don't do that.
Move the multi choice option after more time: currently it is faster to reply using the multichoice feature instead of typing. Or, another possibility, when a competitor replies using multichoice, don't reject the typed answer as too slow.
Anyway nice game, nice idea.
Vet your questions better. I do not want to know who the founder of 'Enterprise Rent-A-Car' is. And saying that John Hanson was the first President of the United States is a joke. But otherwise, this game is really fun!
