How to Play

Control the character by moving the mouse cursor. The direction is indicated by the arrow hovering over the screen. Click LMB to attack and RMB to speed up. Running too often will drain your stamina, preventing you from leveling up. Sometimes it is necessary to avoid a confrontation with a stronger player. Your life consists of several segments – that’s the number of hits you can take. If you are low on health, look for more cubes – upgrading will rejuvenate you.

Tips for Beginners

Do not rush the first attempt; learn movement, timing, and obstacle behavior before chasing a high score.
Watch enemy movement, track curves, or hazard timing for a few seconds before committing to aggressive moves.
Short retries are part of the loop, so treat early mistakes as practice instead of failure.
