As mentioned in Gameplay, Chicken Little: Ace in Action
levels are divided into three types and each type has a different feel and control. While the basics of these controls are the same, the differences really help to set each style apart.
During Ace's levels, your control scheme is a lot like most shooters have been for this system. Your Wii-mote acts as a combination camera-control and sights. Whereever you point your Wii-mote is where you will shoot, and as you move towards the edges of the screen, the camera rotates and Ace turns.
When controlling Runt's tank, the basics are the same, but the camera/aiming mechanism feels a bit more detached from the movement aspect of the controls. Since you are controlling a tank and you can rotate it in any direction, being able to drive around in circles while having your guns wave in wildly different directions feels a lot smoother and ...well like I said, more detached than when controlling Ace.
Abby's hovercraft is probably the most interesting scheme, and was definitely the hardest one to get the hang of. Like Ace and Runt, you point where you want to shoot, and the camera will follow. Like Ace, the camera and movement controls don't feel quite as detached as they do when driving the tank, but the hovercraft has the added bonus of being able to go up and down simply by tilting the Nunchuck up or down. Like I said, this took some getting used to, but once I did, I was able to pilot the hovercraft with great precision.
For all of these modes, you have two types of weapons. Your main weapon is fired with the (B) button and your alternate weapon (the one with the limited ammo) is done with the (A).
Chicken Little: Ace in Action is just a fun game. I doubt many gamers will be able to pick it up and not enjoy the experience. What might throw some people off, however, is the Wii's different control scheme, but with practice and a little bit of time, those issues go away.
