Puzzle time 4D

The fourth installment in this series 3 remains( 5D,6D and 2D)

Nice! Thanks @Manish

It was a little difficult to make way for the block on the right side of the win block to be removed. It was good.

Good traffic puzzle.

Before I evaluate the level, I want to ask you - do you come up with the arrangement of the traffic puzzle pieces yourself, or do you take the basis (arrangement of elements) from another game and then adapt it for mekorama?
The thing is, there are many other games (not mekorama!) that have a lot of levels specifically tailored to this genre. They have a lot of levels and difficulty levels. You could take a puzzle of good difficulty from there and adapt it for mekorama—then it'd be a 4.
But if you came up with absolutely everything yourself, and didn't use designs from other games, then this is a very good puzzle, worth a 5.

That's why I'm hoping for an honest answer to my question. Then I'll give you a rating.
