Superb
Very awesome flash, I found no major problems really and the graphics/controls were perfect. (Also I love how you added Web Spider in it, MMX4 was the first mega man game I ever played)
Aaaand for all of those people complaining about it being too difficult, then just one thing.. learn to dodge. Honestly its not just go in and charge your laser and fire. you need to learn the enemies movements and attacks and learn how to dodge then attack when there's an opening.
