About This Game

One spark. Then thousands.

You throw a single spark of light at the top of the board. It hits a glass pin and sounds a bell. It finds a prism and splits into three: red, green, and blue. These prisms find other pins and prisms, and somewhere down below, two of them meet and turn yellow. By gathering all three colors together, you get white light, the largest.

By the time everything lands, one spark will have turned into thousands, and the board will play a little melody for you. Then you throw the next one, a little more cleverly.

How the Run Works

Beat the target and you pick a new peg for free, spend your Shards in the shop, and place your pegs right onto the board, wherever you think they'll do the most good. Miss it and the run is over. A full run is eight acts of three rounds, and parts of the board move: rings turn, a pendulum swings, rows slide. No two drops land the same way.

Eclipses change the rules.

The final round of each act is an Eclipse, a more challenging round with one modified rule. Wind blows light sideways, a whirlwind swirls it across the board, darkness obscures your target, or every spark changes color. You see these at the beginning of the act, so you can prepare, and each eclipse has its own sky. Beat it, and you choose a Crystal.

Sounds good on purpose.

Each hit plays a note, and the notes always combine and fall into a gentle rhythm, so even a chaotic cascade sounds like music, not noise. Red sparks play on a marimba, green sparks on bells, blue sparks on a soft background, and white light sings a chorus. Play with sound.

Made of Light.

There are no illustrations in the game. All you see is simulated physics: glowing glass, colored trails, and colors that actually add up on the screen, so the overlap of red and green light appears as yellow.

Supernova

Defeat the last Eclipse, and you get another drop, targetless. Your spark explodes into all colors at once, and every piece on your board is charged: prisms disintegrate everything they reach, all the way to the bottom. This is your entire run board, lit up in one go.

What's inside

• Over 70 kinds of pegs. Prisms, filters and mixers, novas that double every beam, springs, portals, mirrors, and black holes that swallow everything and spit out one heavy white spark.

• Peg levels. Level up a kind and every one of them on your board gets stronger for the rest of the run.

• Over 200 Crystals. Rule-benders: prisms that split four ways, white light that throws off extra sparks, one more drop when you fall short.

• Over 30 Eclipses, from gentle ones early in a run to harsh ones at the end.

• More boards, each its own shape, and your own boards to build.

• The Constellation. Every run earns XP, won or lost, and each level lights a star in a night sky and unlocks new pegs and Crystals. It gives you more to play with, not bigger numbers.

• Endless mode, Challenges and 8 difficulty levels for after your first win, and a Calm mode to just watch and listen.

• Controller support, Steam Deck, Achievements and 6 languages.
