Sometimes one great idea is enough to take a game from okay to great. That's exactly the case here - though the custom weapon system is a bit clunky, it affords you a lot of options to mess around with allowing you to tailor your guns to your tastes and/or what's needed in the moment. It takes what is otherwise a fairly boilerplate action platformer in the vein of Mega Man and gives you something to chew on as you work through it. It's a quality system worth engaging with in a serviceable game.
