Wormhole

A wormhole is a hypothetical topological feature that would fundamentally be a shortcut through space time. A wormhole is much like a tunnel with two ends, each in separate points in space time.

For a simplified notion of a wormhole, visualize space as a two-dimensional (2D) surface. In this case, a wormhole can be pictured as a hole in that surface that leads into a 3D tube (the inside surface of a cylinder). This tube then re-emerges at another location on the 2D surface with a similar hole as the entrance. An actual wormhole would be analogous to this, but with the spatial dimensions raised by one. For example, instead of circular holes on a 2D plane, the entry and exit points could be visualized as spheres in 3D space.

In "The Cucaracha: A Break In Time", wormhole is the main feature of this game, in order to travel through various eras, player will have to seek ways to find/create wormhole to resolve his situation.

The protagonist "Toby" who is a scientist, creates a time machine by an accident, and gets lost in the past. He finds himself stuck in a cave, and soon he finds out that he has been teleported to "Stone Age" era.
