Spoiler: Short hints: Here are the steps: ①P must push 2 balls and then stuck somewhere. ②Try to save the highest R. ③R should walk on B's head. ④Save the last R.(This R will go to the end)
@I_am_Bot the tricky things are... Spoiler well,the central draggable has two functions: 1- with B raise the draggable & R would be released & 2- when that draggable is up B & R can climb or go down a brick Hope it helps you...if not I'll make you a movie
Fun long adventure, although nail biting at the end as R took three attempts to get through to the finish.
@delator77 thanks for listing the tricky parts. I still have no idea though haha. But don't take the trouble to make the movie. I guess this level is out of my brain's scope.
