Roundel Color Jump

Roundel is a tower of glass: a night glasshouse at the bottom, then a clock loft, a bell tower, lantern-lit roofs, a gallery in the clouds and an observatory at the top. Its windows turn on their own, and they let through only light of their own color.

Tap to hop a glass bead up a tower of turning stained-glass gates. Pass only through your own color; prisms let you pick the next one.

Tap, click or press Space to hop; the bead falls back between hops. The gates turn on their own, and you may pass a gate only through panes of the same color as your bead: touching any other color breaks it, and so does dropping too far below your highest point. The panes of your color on the gates ahead glow, and every color carries its own mark (triangle, ring, two bars, cross) on the bead and on the glass. Changers between the gates set your next color: a glass drop gives exactly the color it shows, and from stage 2 a turning prism gives the color of the facet that faces down at the moment you touch it. Pass the next gate before the ring around your bead runs out to keep your Flow streak; every three gates in a row raise the multiplier, up to x5. Gems in the middle of a gate and close passes add points. Every stage ends with a Rose window; passing it takes you to the next place, with new kinds of gates and a faster turn. Each stage gives you one spare bead: the first break forms a new bead under the gate, and every Rose window gives the spare back.
