Echo Line

Draw a glowing path. Sound races along marble rooms, bounces, drains — reach the receiver before energy fades.

Echo Line is a rhythm-puzzle for iPhone: draw a line with your finger, then watch and hear sound travel the path.

Reflectors bounce the signal. Absorbers drain energy. Tempo gates open only on the beat. Clear fifty handcrafted rooms across five chapters — Sakura, Marble Nights, Floyd, After Hours, and Metal — each with its own look and ambient bed.

Features • Draw → Play pathing on night marble stages • Reflectors, absorbers, and tempo gates • Five themed chapters (50 levels) • Stars, local progress, and Game Center global board • Achievements and player titles • Ten UI languages (device language, English fallback) • Portrait, short sessions (about 1–3 minutes per level)
