Had a lot of fun with this one, actually was a little sad when I saw that there was only one boss. It's a cool simple game, very nice execution, nice graphics, tight controls and nice music too. My first try I was having a hard time hitting the boss, because of sword range and I thought I could only hit him from the sides, since the sword sprite doesn't follow the up and down directions. But the next time I realized that you should actually spin around the boss while attacking which was pretty neat. I liked the boss fight, had the right amount of content, the one thing I missed was anticipation on the attacks, but that wasn't much of an issue. This is nice, I like it.
