It's an addictive and very well realized puzzle game consisting in a series of
3D isometric boards made of various items (static bricks, teleporters and so
on).
We have to conduct a little black monolith towards the pit that is the end of
each level. The monolith can be moved in the four directions but it doesn't
slip, instead it rolls on the board changing the down face at each step.
The monolith is not a cube (though it splits into two cubes sometimes) so it
features a long and a short move. This makes hard to reach an exact board item
when required. And the things become quite complicated when we face the
appearing and disappearing bricks and other pleasant obstacle.
Graphics and sound effects are simple but very neat. Controls are intuitive.
