@bananasmoothii - I have to agree with @Fendi Rahardian - the slider that the win is connected to, just push the win out and then back in - the level is won without moving B.
I chose to ignore the shortcut and play as intended. It's a nice easy, fun level, . The shortcut is easily fixed.
Played the level the way you intended. Too repetitive with too much waiting. Removing the fence over the win block would stop the extreme shortcut.
