Oh man the early tests when the NPCs would teleport through walls were horrifying, perhaps a ghost enemy can be added in a future version to bring back the scares jajaja!
We actually have a health 'bar' concept that was just about implemented but we didn't get to that point quite yet, rest assured there will def be an update later on, if not a remake in time for the spooky season:)
Good luck with the competition guys!
