Rube Goldberg Machine

This is my first Unity exercise creating a Rube Goldberg machine without any code. With use of just basic geometries, it utilizes the physics engine to create a domino that I tried to spell "hi" at the end.  I tried integrating color, physic material (bounciness), rigid bodies, and constrains. It was a challenging first exercise but I hope to improve with the coming weeks! Build is available on Windows/iOS/WebGL.
