Lockstep Puzzle

One swipe. Both pieces move. The rule is a single line: swipe, and both pieces move in the same direction at once. You cannot steer them separately. But whichever one hits a wall stays put. That gap between them is the whole game — pinning one against a wall so the other can go on alone. About the time that clicks, doors appear. Then ice. Then pits. ■ No tutorial screens Nothing to read. The first level of each chapter is the explanation. Push once the wrong way and the rule simply lands. ■ 120 levels, every one hand-picked Tens of thousands were generated and solved by machine, then filtered on two things: how often the two pieces actually diverge, and whether the level falls apart to the obvious push. Every level has a proven minimum solution. Chapter 1 Walls · 2 Ice · 3 Switches · 4 Pits ■ A quiet game - No ads - No internet needed. Works in airplane mode - No account, no sign-in, no personal data collected - No timers, no daily nagging ■ Stuck? Undo as many times as you like. If you are truly stuck, a hint shows the next single move — never the whole answer. Hints refill a little each day. Three stars only for the minimum solution. Solving and solving well are different things.
