Quantum Path

25 levels solved with quantum rules. Superposition, measurement, entanglement, tunneling and the quantum eraser: each one a real physics idea, each one a puzzle.

Quantum Path is an isometric puzzle game that teaches five rules of quantum physics by letting you play with them. An astronaut explores an alien planet, crossing islands that float in space. Every level is a problem; the solution is using the right quantum rule in the right place.

FIVE RULES • Superposition — Be in more than one place at once. Hold one point down while you move on somewhere else. • Measurement — Measure the uncertain and settle it. Reveal which ground is real. • Entanglement — Two points share one link. Resolve one and its distant partner changes with it. • Tunneling — Pass through a thin barrier. Not every wall, only the marked ones. • Quantum Eraser — Erase yourself out of a wrong outcome and return to the last safe point.

25 LEVELS Each region teaches a new rule, and later regions combine the earlier ones. In the final levels, you decide which rule to use.

CALM AND FAIR No timer pressure, no lives, no penalties. If you fall, the level resets and you try again.

SCIENCE, TOLD RIGHT The rules are never presented as "magic". Entanglement is not a remote control, and measurement is not a gamble. The game builds intuition for the concepts without teaching anything false.
