Agree on transformation and pregnancy, a dog one would be cool too as i love the wolf one, but i prefer having a subm mc than a defiant one, cause damn be abble to beg to go to the farm or go back to town is really useful before you unlock the horse to do that, so as the nature of dog would suggest we could expect a transformation who would upgr the bite damag and subm.i like how the bird transformation makes it so you can actually fly. speaking of transformations, maybe a mermaid/fish person transformation that allows you to breath under water. Ooooh, i saw ther was witch clothes that were part of the halloween event stuff, but what would be cool is being able to learn magics and stuff.
PS
i agree on the pregnancy thing. i want the mc to be able to have kids w/ the love interests at the very least. (it is kinda my fav kink, too...)
