Don't Balance

Excellent level! I really like the mechanics of the level and the stability of its work. And I really like how you applied this pendulum in the game. Like it - thanks!
About the bottom floor:

Spoiler

I fell into your trap downstairs twice. The first time I thought that the bottom ball should be thrown in order for it to help. But this is a trap. The second time I tried to stop in front of the ball was to time it past the zapper. But you hid the low ceiling (wedges), so I accidentally pushed the ball again. cunning author

Yes it was easy as i always struggle to see in the dark areas of a level so that i never saw the ball that caused @Denis Nazin trouble. But I enjoyed moving the balance.

Well,this was a fun & a quite easy level with nice mechanism but I think that I do not understand the purpose of the down ball as I have realized that pushing it or not is irrelevant since you can win in both cases... I have played three times to be sure, two pushing and one without pushing and I have won all three with no problems maybe a red herring? thanks for sharing @Krisma Wijaya

@Denis Nazin - That low ceiling does lead you to push the ball or face Z and it's a trap, but you can still get a winblock as @delator777 mentioned. You can see a similar way in Mekorama Story "level 32 Back Track"

Thanks for playing my level.

Interesting steps for B & fun for me! Very nice.

Interesting level to figure out and a nice balancing mechanism
