This one is interesting, has some Mega Man-esque elements including a stage select and new weapons as you beat bosses. Soundtrack is nice, particularly shining in stage 5. Gameplay itself can feel a bit finicky at times. I don't really like that there are separate buttons for firing forward and backward, but maybe that's just a personal thing. The last stage kinda sucks ass, it's a boss rush where every boss is given more health than originally. Really doesn't strike me as necessary. Aside from that, though, it's pretty fun overall. I think I'd recommend this one.
