I played with the demo for about 15 minutes and found a bug. I'm running ATI 10.10 drivers so I doubt it's my PC.
-Occasionally Megaman won't jump during/after screen scroll.
-When previous glitch occurs it may also scroll the webpage.
I am going to assume the same glitch will occur in IE. I will leave it to you to test that.
As funny as it is seeing Megaman hurl lasers from his mouth I have to agree with Newt.
I will be glad to test it again when you revise it.
