Challenge Up

Don't you understand, level can be hard and challenging without any HIDDEN. Nobody post any hints. If you are stuck I'll post two hints.

Enjoyable short level.

Nice challenge!

A fun short level.

Spoiler

I won without using the upper ball. Is that the intended solution?

Same as @MekaSage

@MekaSage @delator77 Friends, did you mean that? -

Spoiler: Shortcut

Forgive me please, dear author, you probably did not take this into account.
Very stable shortcut - no trick.

But I deliberately went as you wanted - with the upper part. It is not very simple!
And by the way, you can win with only one flag. I got it - but it's not a stable, complex way.

@Denis Nazin Yes!

The stuff you added...

1. Motor Wall as well as Flipper,
2. Automatic Pusher and its locker,
3. Idea of only Auto Slider can help you pass Fence Floor,

...is fun!

I guess Top ball was for confusing to the players, funny but nice stuff used - Stairs, Bricks, Ball Pusher

The work was awesome.

Loved playing around.

Next time avoid the ways to shortcut!

I told you that you can play but not post any hints.

@umarbhatti - Someone pointed out this level as I was away and missed it. Why did you make this level for me?

I played and won with very little effort. I didn't use the ball above B at the start and the other ball may not roll and fall right so that ball appears iffy.
