That was a cool game!  I like the challenge of coordinating the predictable player attack vs the unpredictable enemy movement & their weapons.  Also the benefit of damaging your sword makes it stronger, at the risk of you dying cause your hp is lower.  I couldnt tell if the other equipment had special effects when blue.  I think I would be nice to be able to rearrange them to best take advantage of that.   

The levels were a bit too large for me, it was getting difficult to remember where I had already been,  and a bit more variety in enemies and level layouts would be cool but overall great job!
