Simon Says Swap

I realized that your intended way is a push from the grass. It works stably - that's why 5! Thank you.
The path under the wedge is very seductive, it worked the first time so I decided that it was the right one. But I was wrong. He is very tempting, it seems that you allude to him with all the blocks. On this I was wrong.
Good logic and design

@Denis Nazin.

What do you mean push from the grass?

R push from the stair to the wedge is the intended. P can release R once R gets stuck under the wedge.

Nice logic level I use P with co-op B to push lower ball is easier than use R is too long
