Fix The Way

Spoiler: Note

How deep is a hole?
When B is in the up-left corner,
Up metal, left metal: 1
Up draggable, left metal: 2
Up metal, left draggable: 3
Up draggable, left draggable: 4

Wow! This is really COOL!! A classic maze but with an original idea (I have never seen such an idea). And the logic is very cool!!
The only inconvenience is that in some holes it is difficult to see and it is difficult to calculate how deep. This is the only inconvenience. Everything else is SUPER!!!
This is one of the best original logic levels in recent times! WELL DONE! Of course 5! Thank you

P.S. And by the way, I forgot to thank you and praise you for the good and stable mechanism for feeding the balls. It is built correctly and the optimal blocks for correct ball feeding are selected - well done

Indeed a nice idea. I also didn't read your note so I observe the holes and count the blocks and eventually won. Ten balls, none to spare.

Very nice level with a smooth balls pusher mechanism & a good logic maze. Thanks @oiiiriei
