Defeat zombies to keep your speed! Run, jump, and dodge traps to reach the goal. Speed drops if you stop defeating zombies. There are four speed modes. Chill, Dash, Turbo, and Hyper. Chill is too slow to clear the stage. Some obstacles cannot be passed at low speed. Defeating zombies keeps your speed and mode. Lose speed, and the challenge gets harder. Higher speed means higher difficulty. Stay fast to survive and reach the goal!
