It was pretty nice at times
To be honest though I couldn't help but feel that it was "hit and miss" in a lot of areas. The 8-bit parts at the beginning were good and the music, while not exactly anything I was ecstatic about, did this justice. I'm also glad that you didn't try to make the humor too edgy and random like most parodies on here.
I guess the problems for me began when it switched to the fully animated segments. It was a bit too big of a change of pace an didn't really blend well with the 8-bit parts. If you wanted to do something like this in the future I might suggest sticking to one style throughout the whole flash in order to keep things consistent.
Also there were times where the dialogue felt unnecessary and didn't help much to give this a Mega Man vibe.
Overall though I like the set-up and the fact that you gave the game your own personal spin was nice.
