Select Your World

Pick a city, press Play, and the speedrun begins. Your character auto-runs; you steer with lane switches, jumps and slides to reach the finish line without touching a single coin. The live HUD shows your timer, coin count, and collision state. Every attempt—pass or fail—is recorded.

The Eight Worlds

Master each original city-themed course. Difficulty varies; best times are tracked locally on your device.

New York

Medium difficulty. Navigate the grid of Manhattan streets and dodge the iconic yellow taxis.

Tokyo

Hard difficulty. Weave through neon-lit alleys and avoid vending machines on every corner.

Paris

Easy difficulty. Glide down the Seine embankments and past café storefronts with wide-open lanes.

London

Medium difficulty. Sprint across Westminster and slide between iconic red double-decker buses.

Miami

Easy difficulty. Race down Ocean Drive with smooth, flowing obstacles and plenty of room to maneuver.

Rio

Hard difficulty. Navigate tight mountain-side paths and leaping obstacles in this fast-paced coastal sprint.

On-Screen Run Controls

Once a map loads, the speedrun HUD appears with everything you need to beat the clock.

Digital Speedrun Timer

AI-generated illustration of a game

Large tabular-numeral display shows minutes, seconds and milliseconds live. Counts up the moment you press Play and stops the instant you reach the finish line or touch a coin.

Run Controls

Start, Pause, Restart and Finish Run buttons appear above the timer. Restart resets the current attempt instantly; Finish Run ends a successful zero-coin run early if you choose to.

Coin Counter

Real-time display of coins collected during the current attempt. Stays at zero until the first coin touch. A live feed of every collision against obstacles and coins.

Desktop Controls

Left/Right arrow keys or A/D to move between lanes. Space or Up arrow to jump. Down arrow to slide. R to restart the attempt instantly.

Mobile Controls

Swipe left or right to move between lanes. Swipe up to jump. Swipe down to slide. Tap Restart button to restart the attempt.

Collision Detection

Real-time feedback as your character interacts with the world. Touch a coin—run fails. Reach the finish line with zero coins—run succeeds and time is saved.

Pass or Fail, Instantly

The outcome is simple: touch a coin and the run ends immediately with 'RUN FAILED - COIN COLLECTED'. Reach the finish line with exactly zero coins collected and your final time is saved as a successful run. Every attempt—pass or fail—updates your personal stats (attempts, successful runs, failed runs, coins collected, best time). Your progress is saved locally in your browser, so it persists between visits on the same device.
