A red-hued ghost mode can be turned on, providing some direct competition as you race through the level. It's the addition of this ghost that really allows the mode to shine.
At one point, rather than simply climbing up a stairway, my ghost opponent vaulted up an I-beam and wall-jumped its way past me. I spent the next few minutes attempting to master the ghost's move, and having a lot of fun at failing miserably. Users will be able to share ghosts, as well as download the ghosts of the top online leaders."
