I was responsible for the character designs in Ori and the Blind Forest. The most important one was for the main character itself. I spent a lot of time and iterations to end up with the Ori we were happy with in the end. It was important to me that the design would reflect the character for each one of them, but to also make them work within the rules and challenges of the game. For Ori that meant that the design had to be very readable, even in motion and when very small on the screen.
