Clever idea and well executed, the music fits quite well too.
One minor addition would be to show "out of how many" on the game over screen, my first run I got 4 right and thought I got them all because I wasn't paying attention that there were 5. Maybe also show which ones you got right/wrong on the end screen.
Fun though, I could see this scaling as you play it - add more parameters as you go. Great job.
