It's great, but not for the right reasons.
Graphics: Unfortunately, I have to give graphics a zero simply because they aren't your's.
Style: It plays like Megaman, but really souped down. As a Flash game goes, it's extensive and handles well, but in comparison to Megaman, it doesn't have the same polished flair as the other more recent Capcom titles. I like the ability to customize controls.
Sound: I don't play Flash games with the sound on, mostly because my speakers are a bit bonkers. Also, 90 percent of submissions to this site use lame Emo tracks that usually result in a brick being thrown through my speakers.
Violence: I always skip explaining such a superficial judging physic.
Interactivity: Spot. On. It has the feel and playability that I would expect from a Megaman series. Full marks for making a solid piece of code.
Humor: See violence.
Overall: Half of every Flash animation is graphics and animation, and seeing as this game uses neither of your own creation, I cannot attribute half the score towards that. Instead, I'll dwell on the programming, gameplay, and story. The story is odd, I have difficulty following it, but then again, I don't play Flash games to experience a jawdropping plot. Programming is thorough, effective, and is solid. This is a phenomenal Flash game, only if the visuals were of your own creation. Regardless, I expect this one to score really well, and was at least entertained while playing it.
