How to play
Goal: sweep the beam onto each spark on the rim and
hold it there for a moment to catch it, before the spark burns out.
Turn: hold the left or right side of the board, or press ← →
(or A / D). The mirror turns while you hold.
The catch: the beam swings twice as far as the mirror does. That is
the whole game — you will overshoot, and settling back onto a spark is the skill.
Legend: cyan ring = a spark, and the ring around it is its
fuse running down. Red = nearly out. The bar at the
top is surge: every spark you let burn out fills it, and every catch bleeds it
back down. Surge full ends the run.
Catches in a row build a streak multiplier. Sparks come faster and burn
out sooner as your run goes on — up to a limit, after which they stay at their
hardest.
