I think that you did a great job: difficult but not impossible.
Who can't kill enemies didn't read the instruction [a little help: to kill the enemies easier you should stay on (in the same position of) them and use the shild ever and when the enemy has iust attacked you can attack].
Just a thing: in the 3rd level I can't see the red spikes very well (I died 3 times there XD)
P.S. Sorry for my english, I'm italian
