Brad Herman, Head of DreamLab at DreamWorks Animation, and one of the Oculus Mobile VR Jam 2015 judges, had some nice things to say about Circumpaint over on his web site:
Circumpaint is pixel art painting with your head. At first I was not expecting much, if I want to make art I would really like to use my hands. I ended up animating a pixel dragon breathing fire, it was silly but cute. It made me laugh and want to play a bit more. The developer clearly understand the limitations of trying to paint with your head, I appreciate the choices that they made to deliver a surprisingly satisfactory experience.
