Unit B-17
The hero of the short film. Small, dented, and the only unit still moving when the gravity core lets go.
Origin
One verb, held for a thousand stages.
Most puzzle games give you more verbs as they get harder. Gravity Station keeps exactly one and makes the room more interesting instead. You choose a direction; everything in the chamber obeys it at once. That constraint is what makes a five-piece board hard.
Every hazard we added had to pass the same test: does it change what a direction means, or does it just block a square? Lasers redraw the safe lanes. Portals let a piece leave the board and re-enter it still moving. Black holes turn a wrong slide into a permanent loss. Blocking squares, on their own, did not make the cut.
The short film
The film came second. Once the station had fifty locations and a crew of maintenance robots, it wanted a story, and the story wanted a character small enough to be inside the mechanic rather than above it. That is B-17. The last ninety seconds of the short are the game, played for real.
What is next
The iOS listing, the finished cut of the short, and more chambers. In that order.
Worker class
Carries plating and welds the ring sections. Built for load, not for speed.
Science class
Runs the gravity experiments that made the station famous — and then infamous.
Security class
Heavy chassis, magnetic feet. Keeps working when the floor stops being the floor.
Cargo class
Six legs, four clamps, endless crates between the shuttle bay and the ring.
Service class
Sweeps the corridors nobody visits. Saw the first warning light before anyone else.
