I really do love this game but MAN was it hard to go back to, especially after playing Zero 1 and 2. I really can't point to anything inherintly wrong with Blaster Master; it's level design is solid, music is quite good (save for area 8, that shit sucks), the game has a solid challenge, and exploration is quite fun. But unfortunately, the main issue with the game is the era it was released in. Limited lives (which is a death sentence in metroidvanias), no saving, no map, insta-kills, et cetera. I would love if this game got a modern remaster or something, because the core of a great game is here. But unfortunately, I can only recommend the original Famicom version (with infinite continues).
