As Avani has already said, I can really see this being used for roleplays. An addition to the game like this can certainly encourage players' imagination with hunting, which has been requested in an FH update for a very long time - but cannot happen. Should people learn how to do what you've done, I can definitely see public/private downloadable maps putting in some of these chaseable sprites, and making it easier for a roleplay member to describe their successful or unsuccessful hunt.
Well done Kuri, this is absolutely fantastic! Do keep it up, and I'd love to see what else you have in store to share with the FeralHeart community. <3
