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.
▸ MODE SHIFT THE LIST
Skeeball
Several alleys, physical targets, a limited supply of balls. Your marble was already the right shape for this.
Chomp
A maze, pellets, power pellets and four ghosts, with its own score, clock and music.
Mirror
The phone's front camera takes over. Your face drives it, and there is no marble to roll.
Three exist. Skeeball and Chomp are the two release candidates; Mirror is undecided. What they are all waiting on is the same missing director.
