I'm slightly confused with this premise, if I'm being honest. Seeing that this is an "educational" game, and that it's called Get to Know the Greek Gods, it seems a little backwards to me that the game wants you to already know about the Greek gods. And you actually can't learn anything about the god in question unless you give a correct answer first. I just found myself blindly guessing at most stuff, which gave me no sense of accomplishment or loss when the answer was revealed.
This could be a matter of timing and resources, but it could be useful to at least share a story, or an image, or even just a hint of some kind before you quiz the player on what they know. That would at least give the player the satisfaction of attempting to learn and demonstrate comprehension of a new subject. :)
