The idea behind Trajectory started out being essentially the demo level with a very vanilla backdrop. Then the setting changed to an influence mix between having the feel of going through an animatronic ride, like at Disney World, such as Pirates of the Carribbean or It's a Small World.
Try out the demo today, here at moddb.com!
The full game will be ready in March. It will consist of the basic demo level, 3 difficult themed levels, and potentially a 2 player level. Screens and vids posting up in January. Thanks!
