Wasn't immediately clear what the game objective was so round 1 was more difficult.
Camera moved around faster than I would have liked, I'm not sure you really need camera movement at all and could just do the quiz with input of key presses 1-4 instead.
Could be improve with some audio and/or visual queues if you answer right/wrong, I wasn't very confident in any of my answers and had to check my remaining lives at the start of each level.
