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.
