Frequently Asked Questions

What is Quantum Shift?

A free browser particle puzzle: move with arrow keys and touch blocks to flip red and purple states until each one matches its outline target.

How do I play?

After Play loads the level menu, pick a level. Use arrow keys to move your blue block into particles and toggle their color to match the outline.

What do the outlines mean?

A red outline wants the normal (red) state. A purple outline wants the quantum (purple) state. Touch a particle while overlapping it to flip states.

Is progress saved?

No. This build is session-only with no localStorage saves.

How big is the download?

About ~68 KB of HTML, JavaScript, and inlined level data after you press Play.

Does it work on a phone?

It can load on a phone, but arrow-key movement is the primary control, so a keyboard is the better fit.

Is this open source?

Yes. Adapted from dr5hn/quantam-shift by Darshan Gada under the MIT license. This site build adds noindex, inlines levels.json, and ships LICENSE plus CREDITS next to the engine.
