Short, mind-bending puzzles in non-Euclidean space. Each level breaks a different rule your brain takes for granted. Parallel lines diverge. Rooms are bigger inside. Straight paths curve.
Every puzzle drops you into a space governed by different mathematical rules. Hyperbolic planes where distances grow exponentially. Spherical geometry where every triangle has more than 180 degrees. Toroidal surfaces where walking straight brings you back to where you started, but rotated. You learn by navigating, not reading.
Each level isolates a single geometric property and makes you solve your way through it.
Space grows exponentially. Walk ten steps and you're farther from the start than you'd ever expect. Navigating back requires rethinking distance entirely.
Negative curvatureAll straight lines eventually meet. Triangles have more than 180 degrees. The shortest path between two points curves in ways that feel deliberately wrong.
Positive curvatureWalk forward long enough and you arrive where you started, but rotated. Surfaces connect to themselves in ways that make mapping impossible without rethinking orientation.
Non-trivial topologyLeft and right swap when you cross certain boundaries. Your reflection doesn't match. Objects that were on your left are now on your right. The space is non-orientable.
Non-orientableUnparallel is a 3D puzzle game built for the browser. No plugins, no installs. Just geometry that doesn't play by the rules, and puzzles that make you question everything your brain assumes about space.
