CobaltSprint

CobaltSprint is a fast, neon-soaked endless runner built for one-more-run sessions.

Dash through a glowing cobalt gauntlet, weave between obstacles, and push your reflexes to keep the speed climbing. Every track is a fresh blur of teal and amber light — the further you go, the faster it gets.

WHY YOU'LL KEEP RUNNING
• One-tap controls — instantly playable, endlessly hard to master.
• Pure speed — momentum builds the longer you survive, so every run feels different.
• Neon visuals — a clean, glowing aesthetic of teal and amber on deep navy.
• Track progression — unlock new tracks and chase a best distance on each one.
• Your records, your device — high scores and unlocks are saved locally.

FULLY OFFLINE & PRIVATE
CobaltSprint needs no account and no internet connection. It collects no personal data, shows no ads, and requests no permissions. Your progress is stored only on your device — nothing is ever uploaded.
