The Grand Canyon

The level is cool. Cool idea of the canyon and cool gameplay with tricks and different techniques. I won and This is a level of 5. But! there are some very disappointing places:

Spoiler

1) a very difficult and sometimes unstable path, so the BIGGEST disappointment is the hidden electric shock (zipper) at the end! After a large number of attempts and a difficult path at the very end, a big disappointment. This is the main thing that I did not like. Do not put a test with a restart at the end of a difficult level! This is one of the laws of a good level
2) I really like throwing the bot on the motor. But at your level it's torture! Very unstable - the bot often flies off the level. And you have to repeat difficult tricks at the beginning of the level over and over again
3) the trick - going sideways from the step onto a cubic block (like BB) - this is an unstable and difficult trick. Once - it's bearable. But many times (on such a difficult level) - it's disappointing.
4) there is instability of the balls and the mechanism. The mechanism at the beginning of the level - often does not work. The ball that should push R - sometimes does not roll. The ball on the column for R - also sometimes gets stuck.

In a complex all these places which described in the spoiler - negatively affect the attitude to the level. You are a very talented author! That's why I spent time on this detailed explanation - so that you could improve your levels, in my opinion.

Because of this, unfortunately, I can not rate it, since these places greatly spoil the attitude to the level, in my subjective opinion. But this is only my opinion, perhaps other players will react differently.

Perhaps because I read @Denis Nazin message, and saw the length of the spoiler (without reading it), I had a much better experience. I had a few restarts for the first move, and one because the mechanism didn't work. But then I reached all the stars in one go. I like a challange and understood this to be one. For the motor jump, I first pushed B only one wedge up, then had the right force. I was highly vigilant towards zappers. I made R push a ball by bumping B in to R. Dangerous move, as I had to sent B to a tile next to the zapper. But, R was there first so it worked. After a few easy steps, and being primed by zappers and the BB-like moves to climb a block next to stairs, I anticipated what was coming. One more glorious jump finished the level.

I do agree with Denis, especially on point 1 and 2. Point 3 is not a trick I particularly like, but on phone I find it easy enough to execute. And regarding point 4, my mechanisms are also not always stable.

I liked the theme, design and challenge of the level. Other expectations will make the experience less optimal.

Thank you guys for the feedback

Would have won on my first start if i had used the correct bot for the ball. And of course nothing worked as well on the next few starts . The motor leap and jammed mechanism. I enjoyed it.

I agree with @Denis Nazin 's analysis, but I love high-risk and difficult levels like this one, even though BB's recurring trick is pretty annoying. The design is great.Thank you @Rush
