Characters currently in-game aren't going to change much going forward as the scope of the game needs to be limited. There will be predators in the future who may have more direct interactions with their prey. Game endings will come with the next update, that may be the closest thing to dating I'd plan to do.

Ok, no problem if you don't use them. But here's my ideas
Graveyard/dark spooky area: Ghost or vampire
Forest shrine: Kitsune (Refers to Amelia as her offering)
Cave/underground: Drider
Water: Mermaid (Unique Mechanic of being mostly in the deep water, And you would only be able to really escape when she decides to sleep in shallow water.)
