Toren is gonna be released tomorrow and is an indie action adventure where you play as the Moonchild, climbing the titular tower.
The interesting part is: you start of as an infant and grow older the higher you climb, ending up as a young adult.
You can watch the trailer
here. They show of various age states, but not how she grows up. My guess is there will be no real process between the age states but there will be a few of them to compensate.
