Unlocked the Transform Z for the Cube and created constraints for the Z value between 30 and 48. We need to decide as a team what we are going to do if the ball leaves the space the cube is in or how we can make this fluid and not break the experience.

Added small invisible walls near the bridge to avoid issues with walking into bridge stones preventing movement. Makes for a fluid experience.
Changed Cube Color to something that is easy to see against the background for anomalies.

Play tested Debeer's commit before pushing my changes. Good work.
