Locked Box

I'm not very good with lock levels but I was bored so gave it a real go and got it.

@Kayan - Forgot to mention - the QR code on your card is very small. Some players as per myself will get an error while trying to read it. I had the time to zoom into your card and enlarge the QR so it would read on my device but others will just move on to another card. There is a tool that will prevent the QR code being small. If you go to MekoStudio.com and look under the 'Customizer' option, you can optimize the QR code on the card so it's full size. Problem solved.

@gmacpro Thanks for rating and sharing this with me ! I finally understood how people managed to replace grass with desert effect

Here a link to a bigger QR code for those who can't read the first one : https://imgur.com/a/g6uHfgL
Next time I'll directly do it !

Very nice lock puzzle! I usually don't like such kind of levels, so I add an extra star for it. Thanks for sharing

Hints please...i didn't get it even i saw the clues...please give some hints..

Spoiler

The small cube gives you all the positions of each draggable you have to pull out from the bigger one in order to retrieve the key from it and win.
The first thing you need to do is to associate each face of the small cube with those of the larger one, and then, you need to determine which draggable to pull out from each face.

I hope that helped

Excellent lock level! Thanks for sharing!
