@Lang Tao Jin Spoiler Only 3 Balls were needed. Autopilot Ball, Path Maker Ball (Pushed one) and another Path Maker Ball (Dropped one) Which means, No dark Stair was needed. Still fun to play!
Good game. Small but I liked it. The most important thing is that at this level I managed to get on the ball and very easily. But on your previous level, I couldn't get on the second ball. I do not know why. Thank you. I like it
