I liked the swinging effect of the player and the nice background. But the start was a little to fast and the font not so good to read, so that I couln't read you nice story at first try. And sadly I didn't get even one hit in. I think it is a little too hard for me.
But stay on the swining mechanic. That's really fun! With more hit impact on the enemy I could see how this could be a fun loop.
