The hook

Mode shifts

The mountain is not the content. The mountain is the thing that keeps interrupting itself.

Three modes are built and playable. What is not built is the part that matters most: the director that smash-cuts you into one mid-roll, hands the marble across, takes a result back, and drops you into the level where you left off. Today each one launches on its own from a developer menu.

So this is three-quarters of the idea, working, with the join still missing.
