When the loop ends, a ghost replays your exact moves - so you build a herd of unicorns to hold every switch at once. The rainbows aren’t scenery: they’re the wiring. Route beams through mirrors, prisms, and color filters, then walk across the beam you just routed. Your body blocks beams - but never the one you’re standing on.</p>\n<p><strong>Controls</strong><br>\nDesktop: <code>←→ / A / D</code> move · <code>↑ / W / Z / Space</code> jump · <code>↓ / S / X</code> drop star · <code>R / Enter</code> new loop · <code>Q / Backspace</code> undo · <code>Shift / Tab</code> fast-forward · <code>T</code> restart · <code>M</code> mute · <code>Esc</code> pause<br>\nMobile: the screen becomes a <strong>Game Boy</strong> - D-pad (move / jump / drop), magenta A (jump), pills for undo / pause / fast-forward / loop. Screen tap = jump / start / skip.</p>\n<p><strong>Why it sticks</strong></p>\n<ul>\n<li>The music <em>is</em> the clock - exactly 13.000 seconds, restarts every loop, world pulses with each beat (even at 5x speed)</li>\n<li>Ghost route dots show exactly where every unicorn walks - plan multi-loop timing visually</li>\n<li>The “loan bridge” level: ghost holds a mirror to make a rainbow bridge; you cross, then it steps off so the beam swings to open the gate</li>\n<li>Par+1 unicorns per level; overspending draws from a 13-unicorn reserve. Finish at par = 1 unicorn returned. Reserve 13/13 at the end</li>\n<li>13 KB. One file. No images, fonts, or libraries. Runs offline.</li>\n</ul>\n<p><strong>Tech details</strong></p>\n<ul>\n<li>Deterministic: ghost <em>k</em> collides only with ghosts 0..k-1; devices driven by ordered input tapes; door state lags receivers by one frame = pure function, no fixpoint iteration</li>\n<li>Music IS the clock: 13.000 s rendered once into a single AudioBuffer, restarted every loop so it never desyncs</li>\n<li>13 beats, one accent per second - 13/4 meter = free cosmic horror</li>\n<li>Procedural unicorn, beams, particles, sky, audio - zero assets, zero libraries, runs offline</li>\n<li>13,308 bytes gzipped, one self-contained HTML file. Tested by a bot that plays all 13 chapters to the ending at par - reserve 13/13. !!!</li>\n</ul>\n","source":"Mvnshi/js13k-2026","stars":0,"dc":"https://mvnshi.github.io/js13k-2026/","languages":{"JavaScript":129528}}
