Power of Illusion makes heavy use of the Nintendo 3DS's stylus. By tapping the item icons exist in every level, you'll be able to "paint" (trace) those items into existence, including cliffs, cannons, and floating platforms. The more precisely you trace, the better for Mickey. A flawlessly-painted cannon will only damage Mickey's enemies, for instance, but if you mess up the painting, the cannon will be a danger to everyone in the area. Sometimes you'll need to erase objects, which is done by spreading thinner. Again, the stylus comes into play here.
