Slider Teleport

One main demo is teleportation via a slider. And two bonus demos with R. One of the bonus demos borrowed from @Karen 2.0. Thanks a lot for the inspiration! And the initial idea.

My early research and my very first "slider and rail" idea:

Spoiler: Video walkthrough

Big request !! - if someone has already seen this effect on a level or demo, please tell me and give me links. Thanks. I mean the basic demo - teleporting B via the slider

I like this one

@Labyrenight
Thank you my dear friend!! I'm happy that you liked it. By the way, this can be done not only with B! Teleportation through the slider is possible with both R and L!

I forgot to indicate the TRICK !!
This is a slider freeze
or quick slider
or a sticky slider.

Thanks a lot to my friends. They gave me a link to the old level, where teleportation of iron through a slider was used. Here is this level:

Very good demo

@Mr Lemon
Thank you friend! I think there has been a lot of information and ideas for new levels lately. And there will be many new ideas for you. The main thing is that you have free time

It's pretty funny to watch the R bots fall and then seem to disappear.

@MekaSage
And indeed!
Well noticed!
Big, big thank you friend!

Cool teleport level... спасибо @Denis Nazin

@delator77
Thanks a lot my friend!!

@Denis Nazin время есть но я не полностью трачу его в мекораму а идей много, осталось их только грамотно воплотить в жизнь

@Mr Lemon
Вот-вот, именно! Идей много , но самое сложное их корректная стабильная презентация! Это самое сложное и на это уходит больше всего времени. Абсолютно согласен!! Если что , пиши мне в личку, что смогу - помогу
