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.
