Nightmare Castle Now Better Than Ever

Since the only things on my to do list were to add more decoration to the level and to add keys and doors, those are now done. Things like patches of dirt and wooden planks make the castle feel decrepit, while the pillars, tomb stones, and shelfs make the place feel abandoned. As for the key and doors, you must look around the level for keys, then use the E key on the keyboard to open a door with it. Only one door leads to the way out... The opening dungeon also tutorializes this mechanic.
