Zivline: Thread Dash

Zivline: Thread Dash is a relaxing line-drawing physics puzzle game.
Your task is to draw a continuous smooth thread on the screen. The small ball will roll strictly along the line you draw.
You need to carefully design the trajectory, avoid all black dot obstacles on the field, and make sure the ball rolls steadily into the black target slot at the bottom.
If your line is bumpy or the ball hits any obstacle, you will fail the level.
Every stage brings a brand-new layout. As you keep clearing puzzles, the difficulty will keep rising, which will test your hand stability and route planning.
Draw precise paths, dodge all hazards, and lead the ball to land safely in the destination!
