So, you can place cubes on the stage. You can place them EVERYWERE you want. You can choose ANY cube you want using arrow keys. There are 6 types of cubes: 1. Cube, that goes forward every time (automatic cube); 2. Cube, that need a signal to go; 3. Cube, that makes a signal after pressing space / after bening hitted by other cube; 4. Cube, that works like wires; 5. Cube, that can create automatic cubes; 6. Cube, that can rotate any moving cube.
Thanks to the Cell Machine and game of life for original idea, but Mechanical Cube and Cell Machine are not same.
