A pretty big leap from the prequel in several ways. The developers had really mastered the MD hardware at this point and their talent and attention to detail is visible throughout every aspect of the game, from the tough and intimidating bosses to the impressive and catchy FM soundtrack. I thought the great people at Technosoft overdid it a bit when trying to make up for the low difficulty of the prequel, to the point where some parts become a chore to play unless you know them well and have the special charge-up weapon ready, but it does still take first place in the series for me. I should add that there's some slowdown here and there, so play the Saturn version if that bothers you.
