BOX and KEY

@d'SUKI Thank you thank you thank you !!)
I tried very hard)

@Meak Thank you very much!! I am very happy!) I did not work in vain

@Pratik Bhalerao
By the way !! I specially made 2 sliders in the box.
The left one is for a beginner.
Right - for a professional (with a trick)

@Denis Nazin

You could have added a Star there.

If left side has Stair why use trick at right side?

@Pratik Bhalerao
Will explain.
It was fundamentally important for me that everything in the box was symmetrical.
And left the near slider for those who like magic tricks)
Easier - with a ladder, but more difficult to reach. To him you need to go through a hidden passage at the far wall.
A beginner won't take a star. there are people who need to collect all the stars.
I'm one of those!)

The gameplay is not difficult but the design is simply brilliant... спасибо @Denis Nazin

@delator77 Thank you very much great friend! I am very pleased! And thanks separately - for the Russian СПАСИБО)))

Firstly, the box itself is very beautiful. It is a very nice design.
Also, the various use of sliders makes it particularly attractive.
However,

Spoiler

You can of course force the lid open without using the key, once the latches on either side are moved.

which is how I opened it the first time to see the key mechanism at work.
As for once you're inside

Spoiler

it doesn't take long to find the stairs leading to the dragable

and

Spoiler

using the same draggable to stop the upward spikey flower is a great idea

.
But

Spoiler

once I've got B onto the central slider

and re-closed the lid I cannot get the WIN triggered. How the heck can I touch the WIN from this position?

@IceBlade
Hello!
I don't know how to make spoilers yet.
SPOILER!!
When you're on the center slider, slide it out of the box!
And be careful when you close! Only one block B will not fall!
Good luck)

@Denis Nazin oh dur I am so dumb. I spent all my time trying to position B so the box would hit him.
Argh. I hate being this dumb lol.
Thanks again, beautiful level.

@IceBlade Thanks for the game !!
It's nice that at least someone here can be surprised)
I really hoped it would be an interesting move.

@Denis Nazin To make a Spoiler, look in the toolbar when typing a comment, and click on the +.

@Jom THANK YOU!!!!!

I'm currently downloading some of your levels and I'm excited. This level is also great in terms of technology and design. On the other hand, my attempts are to be called rather bad. I look forward to further levels from you.

@BlueDragon Thank you!!!!!!
