Decent enough. Mega Man 9 has alot more BS, but this game way too forgettable, and while I fucking adore Mega Man 2, I really do think they should've improved on MM8 instead of going back to the series's roots. I'll just repeat my Mega man 5 review here:

This is the mega man game of all time. It was thought of, produced, published then sold. What a game.
