you need a constrain attribute everytime you touch the screen to a certain position... i'd need to try out a tech demo for myself to give an exact way of doing it...but it is more than do-able in gamesalad in my personal opinion
Im thinking of something like 2 actors one the dotted line the other the plane.. then when you touch the screen you draw out the dotted line.... then get the plane actor to follow the path of the dotted line at a certain speed...setting speed to a set integer which over time/score will increase making the game harder.
