Spoiler: How To Make The Ball Fall

There are two ways to make the ball fall, but the intended and most controlled one is where R for COMPLETELY unknown reasons walks down the stairs turns around before it steps on the grass and goes back up again!! In order to achieve this R has to walk down the stairs in a way that can be achieved by making him turn right at the top of the stairs before descending the stairs AND the slider next to the stairs has to be in the middle position too (because his head touches it on the way down).

PS It's not THAT hard to solve... but it's going to be utter coincidence that you solved it. If you don't believe that then please study the level hard BEFORE attempting to solve it.

i don't think any thing happen after it squeezed R, R just come back out again.

@TR O So, did you solve it?

@Aleric I did, but

Spoiler

didn't by squeezing R I remember.
