This is a really beautiful game! You put a lot of work into making sure the materials all played nice with your game engine's renderer. The sound design is also immaculate, from the whoosh of the wind to the clink of the ball when it hits a surface. I would have liked to see a wider range of situations that affect how the ball rolls. I really liked how the steam vents blast the ball into the sky, and would like to see more of that if you continue with this project.
