Ghost campfire minigame idea (Patreon)

This weekend I've figured out how to move towards a point, this could come handy for enemies following the player or the mouse pointer. Now the question is: how to make it interesting.
My initial idea was the player must avoid the ghosts by switching sits, it didn't come out as interesting as I've imagined. Now I'm looking for a better idea.

The code is in the attachments, give it a try and let me know if you have any ideas what to make out of it.
