Cool art!!
That was one of the coolest art i've seen for a flash game!! Great work! Effects for also cool.
One thing you could work on is the stamina thing. Loss in stamina doesn't have to be the death of Gandalf. Maybe you should make hime immobile until stamina returns. Which brings me to the next suggestion: When not moving or attacking, stamina should gradually increase. It would make the game a little more enjoyable. Also it got boring after dying a couple of times. maybe you could add more attacks, more levels, and more enemies, like orcs and stuff. And where the heck is Golum?!?
