Every follower gets an apartment.
Twenty followers, and a new floor goes up. Five thousand, and it's taller than any building on Earth. The tower is built in daily episodes on Instagram, and it lives on its own clock: lights go on in the evening, residents head out in the morning. Type your name above and the camera flies to your window.
A tower built out of followers.

Follow
Every follower gets exactly one apartment. Yours is built in the very next episode, with your name on the doorbell.

Twenty followers = one floor
Each floor is 3.3 metres and holds 20 apartments around the core. Every 10 floors form a block with its own theme.

Milestones unlock upgrades
Every follower goal unlocks something new for the tower. The next five goals are public, everything after that stays locked until you get us there.
Self-sufficiency is how much of daily life happens inside the tower. 0 % = everyone leaves for everything: groceries, work, the doctor. Every unlock brings a piece of life inside, and you can watch it: fewer residents walk out of the gate.
Every milestone unlocks something new.
Upgrades are tied to follower counts. Reach the number, and the tower gets it in the next episode. Only the next five are public. The rest stays locked.
The landmarks on the way up.
Every 20 followers add 3.3 metres. These are the buildings and mountains the tower passes.
Seven eras. One tower.
From a house in a field to a station in space. Each era changes what the tower is and what life inside it looks like.
One episode a day.
Every episode adds the new residents, shows a few apartments from above and reveals what the tower unlocks next.
