I feel like you took almost all of the challenge out of the quiz by including the option to type out "sword," "claymore," etc. to fill in all weapons of that type. You also gave waaay too much time.
If you were to type sword, claymore, and spear, then that would give you a FRACTION of the answers. Specifically, with these quizzes I opted to give more leeway to make it easier for people. I'll put the time at a capped 11 minutes =)
