Sorry, but...
Look, for a demo, this is reasonable, but it's still clunky. Your animation is good, but the game is too easy. On the off chance you do miss the ball, you probably won't have your paddle close enough to where the ball spawns to catch it. If it spawned in one place, this wouldn't be a problem, but it goes to basically the opposite side every time. MIss the spawn, and you'll probably miss the next one too, trying to get to the first. Finally... if you're going to make a question system, instead of giving someone a game over if they get it wrong, thereby making all other progress inconsequential, try taking away just one life. Not everyone likes breakout AND knows their boy bands.
