Sonic Chaos — About this game
Run across platforms, build speed on open ground and jump past enemies and gaps. A fast approach still needs a safe landing, so read the next stretch before committing to a leap. Check the route below and the way between nearby platforms before moving on. Remember passages already visited and avoid committing to a drop until the next landing is clear. Looking ahead keeps exploration from turning into a series of hurried jumps.
