How to play

Your piece moves immediately. The echo follows your previous input one turn later. Reach both numbered exits at the same time. Waiting advances the echo while you stay still; a blocked input still counts as a turn.

Purchase and restore

The first 10 puzzles are free. A one-time purchase unlocks the remaining puzzles, which open in order. To restore a previous purchase, open Settings and choose Purchase and restore, using the Apple Account that made the purchase. An internet connection is required.

Settings and saved progress

Open the gear on the game screen to change language, sound, and haptics. Your current attempt and best scores are saved locally. Deleting the app removes its local data; offloading retains it.
