About:
A phone-first action game in the spirit of the 2000s Flash classics, made in-house for Leetdom. The skyline's glassy gleam globes have slipped their moorings, and a lantern courier has eight rooftops to quiet before sunrise. Every light-thread travels straight upward. A struck globe divides into two smaller globes, and the smallest fragments finally dissolve into glint. Reading each bounce and keeping a safe lane matter more than firing wildly.
The eight original stages add split-level eaves, narrow glass arcades, crosswinds and increasingly crowded globe families. Three sparks protect each attempt. Quick consecutive hits build a score multiplier, while every sixth split drops one of three charms: Quickcast briefly carries three fast threads, a rain dial restores nine seconds, and an amber ward absorbs one collision. Each roof awards up to three stars for a clean, quick clear, unlocks the next roof, and saves local best progress.
Everything in the game is original and generated in code: the courier, globes, rooftop scenery, particles and interface are procedural canvas art, and the bells, casts and ambient melody are synthesized with WebAudio. There are no downloaded images, fonts, music or sound effects.

Phone check: 2026-10-01 staging QA: 39 deterministic core assertions cover movement, bounds, casting, swept projectile collision, globe splitting, contact invulnerability, ward protection, timeout and clear/star outcomes. A 640-run sweep-and-cast simulation clears stage 1 at 95% for both profiles, then ramps to 22.5% newcomer / 45% steady on stage 7 and 2.5% / 25% on the finale. Serialized Chromium passed real CDP touch at 390x844 and 844x390, simultaneous move-and-cast touch, mouse and keyboard at 1280x800, visibility pause, blocked localStorage, level-clear/advance, game-over and one-tap retry; zero console errors, page errors, failed requests or external requests. Offline 20 s WebAudio renders: full mix peak -10.0 dBFS, effects RMS -32.1 dBFS, music RMS -49.5 dBFS (17.4 dB below effects), and effects-only output is truly silent 67.0% of the render. Title, gameplay, pause, game-over, level-clear, landscape and 360x270 tile captures were visually inspected.
