Well, first I tried female logic, but as always that didn't work. Then I tried ball logic. That worked wonders. Nice trick level.
I went the same way as the @Block builder at the first. but once I accidentally solved it. I tried several times to get the right time moving and touching the point of the falling ball. this is very interesting And has a dumb solution Thank's
my dear friend @delator77 It's very comfortable and very hard.It's something like a claustrophobia trick. Of course, here's the tight space, the space between the ball and the stairs !!!! good luck
