Hi, thanks for trying it out! The ghosts actually do chase you if they see you in front of them. You can also lose them if you run away long enough. I originally had an entirely different plan for the mask, as well as the whole game. Unfortunately, I spent more time fixing the ghost rig and was forced to rush this game out as a simple pick up an item and return type game. If I had significantly more time before the deadline, I would've spent more time polishing the AI so it can turn very sharply after you dodge its charge at you (and make them sensitive to your footsteps and other noises) and make the game more complex.
