Tunefurrow

Tunefurrow is a rhythm game in a field at dusk. Seeds roll down four furrows toward a row of rings under the moon; hit each seed as it reaches its ring. Every hit plays a note of the melody and plants a flower below the rings, so a good run fills the field with colour.

All eight songs are composed by the game's own code: a scale, a chord progression, drums, bass, pads and a melody built from phrases that repeat like a real tune. The chart is the melody itself, with higher notes in lanes further right.

• Eight songs, from a gentle 88 BPM to a fierce 140 BPM, each unlocked by clearing the one before
• You play the tune: the backing band keeps time, and each hit plays the next melody note
• Long notes and chords arrive in later songs
• Perfect, Great, Good timing, combos up to x2 points, and a grade from D to S per song
• Harmony meter: misses drain it, good hits refill it; empty it and the song fails
• Keyboard or touch: D F J K or arrows, or tap the lanes on a phone held upright

Code and text written with AI assistance; checked by PN Scripts with automated tests. Every shape is drawn and every sound synthesised by code; there are no AI-generated image or audio files.
