Core Gameplay Mechanics
Early reactions. When a hazard appears, react early, since speed leaves little room for late dodges.
Gap weaving. When obstacles cluster, weave through gaps, so you keep momentum.
Collection. When treats appear, grab them if safe, so you gain rewards without risking a crash.
Focus. When the pace rises, stay sharp, so you keep dodging cleanly.
Strategies to Win
React early. Respond to obstacles the moment they appear, since the fish runner leaves little room for late dodges. Reading the course ahead buys reaction time that keeps your run alive.
Weave through gaps. Thread the openings between hazards smoothly, since forcing through ends the run. Anticipating gaps a beat ahead lets you keep momentum.
Collect safely. Grab treats only when the path is clear, since a greedy reach into danger ends the run. Weighing each collection against hazards keeps your score climbing.
Stay focused. Maintain concentration as speed rises, since a lapse causes a crash. A calm approach keeps your reactions crisp deep into the run.
Learn the patterns. Treat runs as practice for hazard timing, since patterns recur. Familiarity turns surprises into predictable obstacles you dodge on reflex.
