Pinch to resize
Fist: gather. Palm: scatter. Touch thumb and index briefly, then open or close to resize. Point and move: draw a snow trail. Make a fist or open palm before switching between drawing and resizing. Peace: change shape. Thumb up and move: attract nearby snow grains. Fist: release and reassemble.
Open both palms, then bring them closer for a stronger snow vortex. Move both hands to guide its centre; one open palm can carry it after activation. Thumb up: slow. Thumb down: colourful blizzard with more snow, faster falling and stronger wind. I Love You sign: a six-petal snow garland.
Pinch thumb and index with the other fingers relaxed, then release to grow a six-arm crystal. Pinch again to rest; existing crystals stay visible while growing branches can extend beyond the screen. Zoom out to see more. For an ice globe, make an OK circle and extend the other three fingers for 0.6 seconds; release before making another. The larger globe clears previous scene-3 crystals and appears at the exact canvas centre. Release OK, then move one hand to guide it smoothly. Hold both fists for about half a second to burst the globe with a shockwave into transparent frost crystals. A quick open-palm swipe left returns to the previous scene; slower movement guides the globe. Pinch growth, two-index connection, the globe and released chips each replace the previous effect. Tilt your wrist to guide growth. Point with both index fingers to connect. Two open palms adjust zoom. Use Pause to pause or resume. Keyboard 1: crystal, 2: connect, 3: guide, 4: pause, 5: zoom, 6: ice globe, 7: release ice.
Right swipe: next scene. Left swipe: previous scene. Buttons work without a camera. Camera stays on your device. Music changes with each scene and fades smoothly between tracks.
