The controls in
Kim Possible: What's the Switch? are very much like any 2D platformer you’ve ever played. Left and right take you forwards and backwards, the X button jumps, pressing it twice will double jump. Square button is your punch, and Circle button fires your weapon. In addition, you get to use their acrobatic skills. L1 and R1 let you handspring left and right to evade enemy attacks. L2 and R2 cycle through your various weapons.
Kim Possible auto saves for you at the end of each mission. It does not, however, have the ability to save at any point in the mission, which would really have been nice. Some missions can take a while to complete, so if you have to go do something in the middle of one, you have to just leave the game running. If you have to turn it off in the middle of a mission, you have to start that mission over from the beginning.
Overall, Kim Possible: What's the Switch? is a very enjoyable platformer. It’s simple enough that just about anyone of any age should be able to complete it, yet complex enough to keep you entertained. My only real complaint is the lack of save points.
