I did not like this game very much.
Most of the stages were frustrating. Especially Frost Man's and Astro Man's stages. The Frost Man stage was one of the worst experiences I've ever had in any videogame and Astro Man's stage is a giant pain in the ass.
Another problem I have with this game is that Mega Man moves so damn slow.
And let's not forget the voice acting. It is laughably bad.
I did like the animations (for the most part) and the graphics. And the music was decent as well. The weapons were pretty alright too.
Still, that isn't nearly enough to save this trainwreck of a game.
