The Haunted Castle is a bonus level found in the Swamps. This is easily escaped, a straight forward path leads to a portal to the next level. But if you're bold enough to enter the castle in the center, then you will have to fight an army of the undead.
The gates to the castle open on their own, and entering the castle spawns 32 grave stones, upon walking over just one of the graves will result in 32 ghouls. Notably there are 3 treasure chests inside the castle which might contain some goodies.
- When you enter a floor with a portal to the Haunted Castle you will hear "the sounds of howling wind"
- You can avoid the ghouls by simply heading straight to the exit portal.
- There's some extra gold hidden behind the walls in the fireplace.
- The ghouls seem to know where you are and attempt to rush you, hiding in one of the towers may get them stuck in the doorway.
