- The homepage lists 23 symmetry worlds and says each placed block is copied by that world's symmetry.
Field notes
The control guide names symmetry markers including 2-fold, 3-fold, and 4-fold axes, mirror planes, inversion centres, and unit cells. Keyboard controls include walking, looking around, jumping, flying, and placing or removing blocks; separate touch controls are described for tablets.
