Performance isn't great in the graveyard (couldn't figure out what was causing it but in the catacombs it's fine on my pc and I'm using a lot worse spec than you!
Did the first ghost attack happen after you went down the hole and walked to the end? After that attack it takes you to a different location and you need to press q to open the lighter back up! I might need to auto activate it again when that happens!
Thanks for giving it a shot though :) I wil make some changes based on your feedback ! Do you have a game submission? Ill make sure to play it later 😁
