Not bad.
Not bad for a first attempt, but there should be more challenge in the game (I'm sure you'll hear this a lot with the first few games you make). Just keep trying. Perhaps you should make it so that the level moves instead of Naruto. Also, look up swapDepths so that if Naruto is in front of an enemy, he actually appears in front, rather than sort of underneath.
All in all, good effort.
