Great idea backtracking each time you die
That alone should have been enough to make this game addicting.
But it wasn't.
Since you are making a variation on one of the most copied games of all time, you need the mechanics to work how we can expect them. But the paddle just didn't deflect the ball on enough of an angle. It boiled down to a game of seeing how gently I could tap my arrow keys.
Also, the ball needs to move faster. Especially with the dying system you have. It would make the game much more exciting.
Finally, you need to create some variation. This is one of the most copied games, right? So show us something different. All the levels are basically the same. Throw in some power-ups or something!
It's definitely a good start, but you have a little ways to go.
