Earth or Soft block is a block that Kye can move through. It will be destroyed once Kye travels through it. Ordinary Square Block is a type of block that Kye can push as long as there is nothing behind it. Rockies move in the sense of the arrow as long as they are not held in place by an obstacle or a sticky block. Rockies will roll around round objects if they are free to move.
Sticky blocks behave like magnets.
They can be very useful to pull objects and to hold moving ones in place. Sliders behave similar to rockies except that they do not roll over round objects. Bouncers move in the sense they point to, and bounce back when they hit an object. Movable objects will be pushed by bouncers. Beasts chase Kye.
