Timing is Key

I liked all the mini games, even the traffic section that I usually dislike. However the completed R section did not appear to be part of my gameplay so i am unsure whether i have completed as designed.

P.S. i have just realised the purpose of the R section so i will revise rating to 5*

Great design,great gameplay,great fun!! Thanks for sharing @Tadashi Suzuki

Great level! It was very fun, mixing logic and ability. There is a small shortcut to avoid R zone and I didn't understand the code zone. I moved two of draggables with the visibility areas and used brute force for the other two.
Thanks!

Spoiler: Shortcut

Autopilot in zone 2. After some tries B jumps/falls in next area.

Quite liked the timing mechanisms in the first part. Plus is that a hidden message??? dba?

@Stew Actually it's the key to unlock the code in last mini-game.

There is no letter 'd'. It's a 'c' with a straight line

In order from lowest to the top:
The line is just... 1
A is 1
B is 2
C is 3

So "clba" code is 3-1-2-1
