One loop through white and black pearls

Rules

Draw one closed loop through the centres of the squares that passes through every pearl. Through a white pearl the loop goes straight, and it turns in the next square on at least one side. On a black pearl the loop turns, and it goes straight through both next squares. The loop never branches or crosses itself; squares without pearls may be skipped. Drag from centre to centre to draw a line; drag along a line to erase it. Long press switches to crosses, “no loop here”: in that mode, tapping a square puts crosses around it.
