How should I go about this? Creating Path with mouse/touch, upon release, follow the movement

I am trying to create a way to make my character follow an outlined path that the player can draw. The player can draw the path and after the finger/mouse has been lifted off/unclicked, the player will follow the path. First time ever attempting something like this and I am fairly new to this so any help would be great,

I will be actively searching the forum in search of a solution :P.

Thanks.
