Here is my long list of ideas
And sorry if I already mentioned something that someone mentioned :/
Scent: Perhaps a scent tracker of friends or something? I really don't think that making it like WQ would be a good idea... but hey, its something
Tracks: I was kinda sad we couldn't make snow tracks or sand tracks... but wouldn't it be a cool idea? c:
Bark/Roar: Again, I was kinda disappointed how we couldn't roar like in IT D: Roaring/barking would make the game more fun, and more realistic c:
Following Eyes: I always liked IT's eyes, how they would follow even at the back of the head ^^
Moving Mouth (without Movie Maker): Another thing from IT XD I really hope that we can talk with our mouths opening, it would be really cool, and better then typing and showing the words on the bottom like Movie Maker D:
*Will be adding more later*
