Badass NES game

[Special K]

Probably came out mid-late NES period because I remember the bosses as being big and impressive. (course Mega Man II had bigass bosses too)

 

Side-scroller. You were a Mech, I believe you could shoot in multiple directions, get a few powerups, the games main gimmick though, was you could flip gravity, often in mid jump, sticking to floor or ceiling as the situation required, you pressed up and jump to flip gravity up, and down and jump vice-versa. Hell of a game. superb controlMy friend and I beat it a few times. What was it called?

Sounds kinda like Low G Man, but I'm probably wrong, that doesn't match exactly what you said.

If memory serves me right, the game was Metalstorm.
