Pretty much the majority of what is said but i definitely think a broomstick mount would be cool, also sell like more wizard/witch type hats, i love those haha. And definitely open club crypt again only make the ghost gani somthing you can buy. Maybe expand deadwood a little bit and add new stuff such as a haunted maze. Lastly, i think you should have a fall tileset that has leaves everywere, similar to how you change it when it's winter, soo most of these idea's were already said but now you know more than one person supports the idea haha

Oh, and a new town would be pointless.. I don't think we need two halloween themed towns
