A space-borne rotation puzzle
Rotate.
Fit.
Fall through.
A wall is closing in. It has a hole shaped like your object’s shadow — at exactly one angle. Spin your shape in 2D, 3D, or a full tesseract in 4D, line up the silhouette, and slip through before it’s too late. Miss once and the run is over.

The core loop
One shadow.
One angle.
One chance.
An object appears
Centered low on screen — a shape in 2D, a solid in 3D, or a tesseract in 4D.
A wall slides in
It carries a hole shaped like your object's silhouette at one exact orientation.
You rotate to match
Two analog pads spin the object continuously until its shadow locks the hole's shape.
Fit or fall
Inside the window when the wall arrives: +1 point, +1 more for a dead-center lock. Outside it: the run ends.
The object library
Every dimension rotates differently.
Regardless of dimension, the hole is always 2D — your object is always projected down to a flat silhouette. The difference is how many ways you have to turn it before that silhouette lines up.
One axis
The silhouette is the object itself. Square, triangle, pentagon, arrow — a single pad, one direction of spin.
Two axes
Cube, tetrahedron, pyramid, prism. A shadow of a solid — a D-pad reaches any orientation in two generators.
Four axes
The tesseract. 4D folds to 3D folds to 2D — nested cubes that turn inside out as you rotate through the fourth dimension.
Controls
Two pads.
One feels human.
Hold a direction to spin, push further to spin faster. Ordinary rotation glows blue — the moment a spin leaves ordinary space and turns through the fourth dimension, it glows magenta, so you can always feel which move you just made.
2D pill · 3D D-pad · 4D adds a second, magenta D-pad on the left
Fit feedback
The hole always tells you the truth.
Far from the fit — keep spinning.
Close. The rim glows to tell you before you commit.
Inside the window right now — pass through if the wall arrives.
Levels & scoring
27 designed levels.
Then it never stops.
Every two fits, you level up. Each band adds shapes before it adds speed, and the fit window narrows as you climb — until the designed campaign runs out and the wall just keeps getting faster, forever.
+1 for a fit
+1 more for a dead-centered precise lock — two points for a clean pass.
One miss ends the run
Best score is saved the moment you beat it — no ads, no friction, just the next attempt.
One more run.
