Kinda wish there was a winter version with Christmas and snow and little snowy hikes
Also we need a super cute Halloween part
There's definitely going to be a halloween part, we've seen some assets for it already. I wouldn't be surprised if halloween was included in every 'step' as you get older, too.
If I recall correctly, I think the creator this time was deciding between autumn or winter as the main theme, but autumn won out. Though I think they also said something like that it was probably for the best, since winter is generally so overtly christmas themed, and it'd be hard to 'get away from' writing wise.
