Bleh.
Do we really need this after the substantially-superior 'Zombie Survival Quiz' that this apparently replaced on the front page? Too-similar questions and a positively NASTY UI make this really tough to give praise to.
Change around the interface, and make the questions linear. It just looks unappealing to have to bounce between the answers. Also, a lot of them don't make sense given the context of the questions.
Cool idea, it just came too close on the heels of the other front-page-rocked quiz, which - in my humble opinion - looked better, and had better-constructed questions. The last bit of info, which is probably the most important: if you're making a quiz game... SPELLING COUNTS! If I have to look at poorly-worded questions in a far-too-basic font, at least make sure the words are spelled correctly.
That's about all I've got. On the 'Pros' side, the result system was cool, and the minigames were a nice touch.
