Excellent driving, Rene. That's a clever, clean design. Even with your pause at the traffic signal (a nice touch visually) your overall track time is better than mine. Here are my lap times (spoiler warning: read "my solution"): moninil.

Well it took me a while but I think I finally passed my driving test: babibal.
One thing I notice we all have in common is (spoiler)starting with a barrel to block the door key so we can get from the left to the right.  How hard would it be if that spot were locked?

[jf]

That is a cool solution, jnz, with some dramatic twists and turns for that 1 crate!

Edit: I tried putting in spoiler text, but the tags didn't work. So, for now, all I will say is that this spot cannot be locked, or else, the puzzle is not solvable. As your 1 moves into place at the end, try that left-to-right and you'll see what I mean -- a physics asymmetricity, if there is such a word.

I did the spoiler text by manually setting the foreground color to be the same as the background.  I hope there is a better way that I am just unaware of.

I see now what you mean.  You can go only one direction with that trick.

*** NEW PUZZLE ***

I'm not exactly sure what this thing is, but you are supposed to click the switch... at the opportune moment. Here it is, a new Medium (?) level puzzle: Click mytahun.

[SM]

Solution to Click:

JUDAGUM

Had to create an exception for a F crate, so I would rate this a "Hard"

[EDIT]
JNZ:  Great solution, I like your different approach to detecting the far right gate trigger.

[jnz]

My solution for Click (mytahun): natufux.  I think I could have made the machine a bit smaller if you had counted down with F crates instead of up with 1s.

[jf]

Counting up with 1's makes it a little more interesting, because it becomes more straight-forward to drop a reversed deck onto the gate, which in turn makes things a little more complicated when carrying the signal across. Here is my solution (here you can see what I mean by "reversed deck" -- or, is this a "forward deck"?): cibitoc.

Interestingly, due to some preconception as puzzle-maker of this puzzle, I am pushing one barrel up to position instead of setting it at the start -- strange.

Edit: I optimized it a bit: dosikyz.

My solution to Click (mytahun): typogus

*** NEW PUZZLE ***

Sometimes, you have to improvise: Queen Sacrifice sasixic.

[Rene]

My solution to Queen Sacrifice (sasixic): gykizov

It is a bit messing around, but it works

[jf]

That makes three interesting solutions to Click (SM, jnz, and Rene), and now, already, a solution to Queen Sacrifice! I especially like the action to handle 0, which I won't describe here, for fear of a spoiler.

Here is my solution to Queen Sacrifice (sasixic): bobakur.

*** NEW PUZZLE ***

Here is a new Medium level puzzle: Eagle Feather kelynoc.

[jnz]

My solution for Eagle Feather (kelynoc): hufivas.  You had to put the matcher all the way at the bottom of the screen, didn't you. 

[Rene]

I brought in a **sorter** for Eagle Feather. That is a bit of an overkill, but hey, when do you get to use it otherwise?

    Solution to Eagle Feather (kelynoc): cygibip

Interesting dozer timer in your solution to Queen Sacrifice, JF!
