I'm actually thinking about buying an xbox 360 controller.
I'm used to gaming with mouse and keyboard, since that's what I grew up using.
I couldn't kill anything with a controller if playing an FPS like BF3 or BC2, but a platformer like this deserves something else.
I've pledged for some games on Kickstarter that would make excellent use of an xbox 360 controller with its optional analog sticks;
Carmageddon Reincarnation, Elite Dangerous and Giana Sisters: Twisted Dreams.
