concept
only flat color cube with black line of the same size

collision detection:
	radius for every cube
	or plane map
	or octree

render:
	only vector shape drawing
	scrolling is easy , x/z y/z
	rotation, rotate the position of cube center
		then rotate cubes. 
		while all cube are aligned and cant be rotated independently
		only rotate one cube.
		while all corner of the cube are the same number with all posibility of +/-
		only one coordinate need to be rotated

world:
	OCTREE ?
		

théory



about octree
	stop divide at cubepixel size
	starting from root node , 
		compare the with the center
		then switch to the child node
		repeat till smallest and you know where you are in the octree
	use node traverse algo scalled for octree and you get node in sorted order
	use limited amount of sibling for collision detection
