TetherSnake

In an electromagnetic grid lab, swipe to steer a red-and-blue magnetic chain snake and tap to switch the head polarity; same-pole orbs repel and push your body away, opposite poles attract—eat three same-color orbs to trigger a magnetic storm that pulls and auto-eats all matching food for bonus points, use two polarity reversals per run to flip every orb, and survive until you hit a wall or yourself while your best score is saved.
