Thank you, hythrian, for the feedback. I've noted everything you mentioned, and will work to make improvements on this and later projects. Thank you for playing, and thank you for the feedback.
One note I will add, and I apologize since this wasn't explicitly mentioned in any tutorial, but the ghost's speed and transparency is determined by their proximity to light. Shining a flashlight at it, or standing near a campfire when the ghost appears will speed the ghost up and make them less visible. I apologize that this wasn't spelled out clearly enough, but I thought I'd add that bit of clarification.
Thank you for taking the time to test my game!
