🎹 Neon Tiles — Flight of the Bumblebee

A neon-styled 4-lane rhythm game built around one of the most famously frantic chromatic showpieces in classical music — 102 measures transcribed from the score, complete with the relentless 16th-note swarms that make the original sound like an actual swarm of bees. The chart pairs the buzzing right-hand line with a fully synced automatic left-hand backing track, so every tap lands inside a real two-handed performance. Cyberpunk visuals with a cyan→magenta gradient palette, ambient drifting tiles on the start and game-over screens, and the Orbitron typeface frame the chaos in proper arcade fashion.

🎮 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.
• Burst tiles — Most tiles fire a rapid two-note burst from a single tap, capturing the chromatic 32nd-note motion.
• Chord tiles — Some tiles play multiple notes at once (octaves and full chords) on a single tap.
• Grace-note tiles — Some tiles play a tiny ornament ~30 ms before the main note.
• Tremolo holds — Some hold tiles alternate two notes continuously while you keep them pressed.
• Pause — Space or P
• Mute / Unmute — M
• Quick start / restart — Press D while any overlay is showing.

✨ Features

🎵 Real Score, Real Pitch

• 102 measures transcribed directly from the published score, capturing the full structure: opening chromatic descents, the central tarantella-style middle section, the high-register climactic run, and the closing cadence.
• Every note plays at its actual pitch, covering an enormous A1 → A7 range — over six octaves — to accommodate both the right-hand swarm and the left-hand bass.
• All chromaticism, ornaments, and rhythmic drive of the original are preserved; only a handful of dotted figures simplified for tappability.
• Tempo is ♩=150 (each game beat = one 8th note = 200 ms) — already quick before any speedup kicks in.

🎶 Four Tile Types Built for the Buzz

The piece is so saturated with 16th and 32nd notes that one-tile-per-note would be physically impossible to tap. The chart packs the score's actual content using four specialized tile types:

• Burst tiles (extras + gap=100) — the dominant tile type. One tap fires a quick two-note chromatic burst spaced 100 ms apart, capturing the etude's iconic neighbor-tone motion (e.g., E→D♯, D→C♯, etc.) without demanding two taps for what's effectively one gesture.
• Chord tiles (extras + gap=0) — One tap fires up to 4 notes simultaneously. Used in the middle section's octave doublings (e.g., E5+E6, A4+A5) and the final climactic chord.
• Grace-note tiles — A short ~30 ms ornament fires before the main note, with both at full volume — captures written grace notes faithfully.
• Tremolo hold tiles — Hold the tile down and the game alternates two notes every ~62.5 ms (e.g., E6 ⇄ F6) for the duration of the hold. Used for the etude's high-register tremolo passages.

🎹 Synchronized Left-Hand Backing Track

• A complete second voice plays itself in the background — 301 note events spanning the full 102-measure piece, scheduled in advance via the Web Audio clock for sample-accurate timing.
• Smart spawn delay: tiles spawn at the top and take ~75% of canvas height to fall to the tap zone, so the LH track is delayed by exactly that fall time at game start. The result: the LH note for "musical time T" sounds when the RH tile for "musical time T" is tapped, not when it spawns.
• The backing track rescales on every difficulty cycle: when BPM bumps up and the melody transposes, the remaining LH events get cancelled and re-scheduled at the new tempo and key. Same applies to pause/resume.
• Includes its own tremolo events for moments where the left hand carries alternating motion.
• The result: when you tap correctly, you're hearing a real two-handed piano performance — not just a melody line.

🚀 Progressive Difficulty + Cycle Flash

• BPM increases by +12.5% per cycle (150 → 168.75 → 187.5 → 206.25...). At a tempo this brisk to begin with, the first speedup is genuinely punishing.
• Each cycle is also transposed up by a whole step (2 semitones), sending the already high notes (A7) into territory beyond a real piano's range.
• Cycle transition flash: every new cycle pops up a centered banner — CYCLE 2 / ♪ +2 · ⚡ +12% — with a scale-and-glow animation, so the moment you survive into harder territory feels earned.

💢 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
