Silhouette is simultaneously a 2D and 3D endless runner in which you control a character running through an oddly lit tunnel, however due to a curse, you and shadow share pain, therefore if your shadow collides with another shadow it is treated like a normal collision with an object.
In regards to the 3D aspect, the player will play the standard endless runner with lane changing and jumping, however due to the addition of the shadow curse, the player must also avoid their shadow colliding with the shadows of obstacles, adding a 2D plane in which the player must also spare some attention.
Why both 2D and 3D? Endless runners are fairly difficult enough as it is, monitoring two bodies adds a degree of complexity and depth as the player must manage two units at once.
