Reach practice
Touch each star with your index fingertip, in order, and hold for a moment. Sit tall and reach with your arm, not your body. The camera stays on your device.
Press “Start with my camera” and allow camera access.
This is browser practice. The full game, with battles, blocking, safe-reach calibration and the lean guard, runs on your computer. Stop and rest if anything hurts, and tell your therapist.
