This has some tight controls. I didn't get real far, but for what I did play there wasn't a whole lot of reason to jump. I could just run across the bottom carrying a cannon dude. I dig his special. I was never able to pick up 3 different guys, tho I tried. It seemed to always remove one? I'm probably doing it wrong. Either way, there's no reason to ever pick up anyone other than the cannon dude. A little variation in their firing pattern would make this much more challenging. Either way the characters are really cool and I can see how a lot could be done with it
