This game was immensely frustrating when I first got it but once I figured it out I loved it. The music is pretty fantastic.

How far are you?

As of now I've entered the city and heading after Armstrong I believe, with the perfect mariachi outfit equipped.

Ah, sounds like second to last level? If that's the case the next boss battle will be fantastic and and is just the most stupidly ridiculous fight in the game.

I always stuck to the outfit that allowed me to hold ten healing kits because I still kind of suck.
