HOLD → DRAW → RELEASE
Draw: Hold the mouse button (or touch), drag a line below the creature, then release. The dotted area is your drawing space.
Bend dots: Drag an orange dot to change your line. Use Starter for a line you can bend without drawing.
Let it ride: Drop the creature onto your route. Downhill builds speed; an upward tip launches. Try to reach the glowing nest. The floating stitch is optional.
The striped gap is air: fly through, but don't draw across it. Keyboard: Tab to a knot, arrows move it; Shift for small moves. Space launches, R reshapes, Z undoes, P pauses.
Your route and momentum are safe here.
