Thank you for your feedback! I agree, the house is large and I should have added a navigation tool like a map.
The bug you saw happened because the ghosts are supposed to patrol around the house at a very high speed when it can't be seen and it switches back to a normal speed when it is seen but that leads to problems like this.
About that rushed story at the end of the intro, it was never meant to be like that and I didn't have enough time so I had to cut down on the features we planned to add. I really really hate that part of the game and we might include in all the features that we didn't have the time to do. after the jam Thanks for playing!
