Sometimes you can hit it with 3 slashes and kill it, other times you miss for endless timespans. also, blocking, as in sooooo many other games, is not smart, you are better off by just klicking again and again until he dies.

Your levels are quite nice though reminds me of Wind Waker which I asume is what you are trying to achieve.

Oh yeah, and before I forget it, on my graphics cart (Radeon 9000)the main menu looked ugly and full of clipping mistakes. I got flimmering triangles over all the models in the scene. (dunno why in the game itself it was allright, might be because de distance between the inverted cartoon layer and the real layer was too small. Dunno bout that though is just a guess.
