This is a very cool game. It's worth continuing to work on it. Here's some thoughts:
* it's hard to tell when the moves have been charged up or not. It would be better if you could visually indicate when these are/aren't charged.
* The idea of including a quiz into the game is pretty neat. If you could make the question set configurable it would be better as your users could study whatever they are interested in studying
* The "you win" page is a bit anti-climactic. Can you make this a bit more exciting?
Improving clarity around charging is on his plan. Its a big issue with the current version.
I'll show him your feedback about the end-game. He was just excited to use document.write()'s side effect of blanking the page if it was the first use of the function. Partly he just wanted to do it because I told him we don't use that function anymore.
They have a method for finding animal doppelgängers, perhaps same approach could work on human faces. There is a demo next to the paragraph about it, quoted below.
