Charge shot or just use a different weapon for the mice. A half jump will line you up to hit the train mets just as they pop out and will position you to avoid their shots. There’s kinda a rhythm to it.I don't know if this applies to the original stage, but how the heck do you get through Charge Man's stage without taking oodles of damage? I just gave up after one too many scurrying rats that duck under my shots and Mets on trains (on... trains), being completely invincible until I'm really close to them, at which point they fire three bullets in a trident shape and crash into me. How do I damage them without taking damage myself? I was really hoping to enjoy myself with this, but that stage just kind of... bites.
