Through The Hypercube

Through the Hypercube is a special intermediate track that only appears in 4-D Bloons (Special Mission).  A Hypercube is a cube inside a cube.  The vertices on the outer cube connect with the corresponding vertices on the inner cube.  The Bloons start on the top square of the outer cube on any vertex and move one unit in the direction away from the observer if they start in the front left vertex.  Then they go to the inner cube and move one more unit in that direction.  Then they go to the lower square of the inner cube and move one more unit in that direction.  Then they go to the lower square of the outer cube, move one unit in the direction, then go up to their starting places and exit.
