easy
this is far from an original idea in fact i know what game you got the original idea from at least i think its raiden trad for super nes. anyway although it is not a original idea far from it actually you did a decent job but i do find that it is rather repetitive after awhile. okay like i said in tittle rather easy i beat all 10 lvls in the first shot.
btw if you like raiden trad but find it too hard then this is the game for you similar but much easyer
