Is there a way to implement a ghost mode where a ghost can replay the best possible solution of a set of data?

My idea is that my 2D platformer game has obstacles in it and a player has to navigate it through obstacles after a few tries to get a set of input data.

So then, I can tell it to change to 'ghost' mode whereby i cant press anything but a ghost will substitute me based on my previous tries and gets an efficient route.

An example of a controller to store keypresses would look something like this.. actions[0].milliseconds = 400 actions[0].action = right pressed actions[1].milliseconds = 1000 actions[1].action = jump pressed actions[2].milliseconds = 1300 actions[2].action = jump released actions[3].milliseconds = 2500 actions[3].action = jump pressed actions[4].milliseconds = 3000 actions[4].action = jump released actions[5].milliseconds = 5330 actions[5].action = right released

..but I have no idea on how to pass this to the 'ghost' character.

I would plan it out like this - Have a player go through the game a few times to get input data - Allow the player to tell the current Active Character to enter Ghost mode. - Reset the Character. This will place them back at the starting position. They will in turn tell their Controllers to reset to millisecond 0 with no keys pressed. - And from here the ghost will show how the player behaves
