Good game, quite a challenge
It took me about ten minutes to complete this game, it's pretty hard until you get to grips with it. Don't listen to the other reviewers saying it was too hard, most of them probably got to level 3 and then quit. It's a little too easy to die on this game, but I enjoyed the challenge. The sounds were a little annoying and so was the sequence before the final boss (since it played every time you had to fight her and couldn't be skipped).
In all it was a good game, so don't worry about it being too hard, it can be beaten. :)
