🎹 Neon Tiles — Golden

A neon-styled 4-lane rhythm game built around an upbeat, anthemic pop track with a wide vocal range and plenty of triplet motion. The chart was transcribed measure-by-measure from sheet music (~80 measures across six structural sections), so what falls down the lanes is the real melodic shape — triplets, syncopation, sustained climaxes, and all. Cyberpunk visuals with a cyan→magenta gradient palette, ambient drifting tiles on the start screen, and the Orbitron typeface give it the proper diva-arrival energy.

🎮 How to Play

• Tap / Click — Tap tiles on mobile, or click them with the mouse on desktop.
• Keyboard — Use A S D F for the four lanes (left → right).
• Hold notes — For taller tiles, keep the key/finger pressed until the tile clears.
• 16th-note pairs — Two tiles spawn on the same row in different lanes; tap both, in either order.
• Triplet staircases — Three tiles spawn diagonally across three consecutive lanes; tap them bottom-up in the visual order they descend.
• Pause — Space or P
• Mute / Unmute — M
• Quick start / restart — Press D while any overlay is showing.

✨ Features

🎵 Real Score, Real Pitch

• ~80 measures transcribed directly from sheet music — six distinct structural sections, with verse, pre-chorus, chorus, and the soaring climactic figure that hits the G6 / A6 range.
• Every note plays at its actual pitch (D4 through A6, full three-octave span) — you're literally performing the melody, not hitting random tones.
• Dotted rhythms, syncopated entries, and sustained cadence holds are all preserved; the only simplifications are a few dotted-eighth+sixteenth figures rendered as straight eighths for tappability.
• Tempo is ♩=120, with each game beat = one 8th note (250 ms).

🎶 Triplet Staircase Tiles — A New Mechanic

• The source melody leans heavily on 8th-note triplets (the iconic G-A-B / G-A-B lift), so the chart introduces a brand new tile type:
  • Three tiles spawn diagonally across three consecutive lanes (A/S/D or S/D/F), forming a staircase that ascends or descends depending on the figure's direction.
  • asc = staircase rises left→right; desc = rises right→left.
  • The bottom-most-first rule naturally enforces the correct tap order, so you physically perform the triplet's contour with your fingers.
• Both 8th-note triplets (compressed into one beat of vertical space) and quarter-note triplets (spread across two beats) are supported.
• Notes within a triplet are played in score order regardless of which lane your fingers lead with — the music stays correct.

👯 16th-Note Pair Tiles

• Pair tiles spawn as two tiles on the same row in non-adjacent lanes (A+D or S+F), forcing both hands.
• The pair automatically alternates diagonals based on what the previous spawn used, so consecutive pairs feel like a dance across the board rather than a repeated pattern.
• Pair pitches play in score order regardless of which tile you hit first.

🚀 Progressive Difficulty

• BPM increases by +12.5% per cycle (120 → 135 → 150 → 165...) — at this tempo, even the first speedup is genuinely demanding.
• Each cycle is also transposed up by a whole step (2 semitones), pushing the high notes (already at A6) into stratospheric territory.

💢 Visible Miss Feedback

• Tap on empty space, hit the wrong tile, release a hold too early, or let any tile fall off-screen — all trigger a red flash at the relevant tile (and a circle pulse at the tap point), held for 450 ms.
• Plays a dissonant low buzz with downward portamento so misses are clearly audible.
• The game ends after the miss display, giving you a clear "what just happened" beat instead of a silent cut to game over.

🎨 Polished Neon Visuals

• Hand-tuned per-lane colors along a cyan → blue → purple → magenta gradient that matches the logo.
• Glowing tube borders, soft outer halos, and scanline textures only inside the active press zone so the tappable area is instantly readable on hold tiles.
• Ambient floating tiles drift continuously down behind the start screen, animating at staggered speeds across the full color palette — no static menu.
• Animated "neon tile" START button that physically slides down the board into the game on press — no jarring screen transitions. Same treatment on the PLAY AGAIN button.
• Score-burst flash animation on every successful hit.

🧠 Smart Lane Distribution

• Lanes are picked dynamically rather than randomly: the algorithm avoids consecutive same-lane spawns and balances left vs. right side usage.
• Pair tiles automatically pick the diagonal that the previous spawn didn't touch.
• Triplet tiles automatically pick the 3-lane group (left-skew or right-skew) that pulls the left/right counters toward equality.

🎯 Forgiving Hold Timing

• Hold tiles only require 75% of the full duration — releasing slightly early s
