I could jump

...
stand on redbrick
push a hidden ball,
then higher ball will fall
because metal half pillar
is shaken by hidden ball...

cool

Claustrophobia / low ceiling is needed.
It is suggested to try it first, each red brick is a necessary reminder.

If you can reach the end but don't know how to get to the stone gate, you can see the hint.

Spoiler: Hint

Go to the red brick two bricks to the right of the starting point and stop. Hear the sound of water or see the ball fall back to the starting point to block the falling ball. Wait for the ball to stay for three seconds and then quickly leave, and then you will get the way to the stone gate.

Then you will understand the meaning of the level title.

(Regarding the floating ball, I have studied it from https://mekoramaforum.com/media/mag1k.18372/ and have done a related level https://mekoramaforum.com/media/ball-bridge.18500/)

Although it is not suggested to watch the video, but still give the video link.

Spoiler: Video

A. Gameplay (+7 stars)

1. red brick at beginning is hidden ball, which will shake another ball ontop.
2. red bricks are clear enough as hint. no video? no problem
   
3. watch the steps carefully, must know correct order of which redbrick to come first and afterward.
4. holding ball with head so B can cross middle stair, to reach red brick below big tower is cool.
5. pretty funny. finish block is head of R, it jump from most top of tower to lower hill with long fence.
6. falling long metal bridge, after drop another ball at other edge of bridge. dont forget to back to start point of bridge before it fall.
7. falling bridge together with long wedge at bottom, become like

@935

play it without video is more fun

Real meaning of adventure

I am happy cz now u know what kind of levels should be upload in the forum and what kind of levels people like

Everything is stable

Like that you provide some helpful backup points

It was fun working out the start and a pause to think worked wonders. The mech was impressive and a nice surprise and good to watch the climb.

Great design & very FUN gameplay... Thanks for sharing @935

wowww very cool...

I wanted so much to give 5 stars, but getting B across the floating ball is iffy. Many attempts missed & he falls below or just as many he makes but the ball doesn't roll into place. This meant a LOT of restarts. Oh, & my first win, R missed & stumbled, triggering the win.
