I gave the level a go and when I got stuck I decided to reverse engineer the level from the end. I can get B or R up to the win area but B can't jump across the falling ball at the end so the ball must be held up. I can't get R to drop the win ball so it must be B but I can't see anyway to get R or B for that matter up to hold the ball. The next problem working backwards, I can get B onto the rail to go up but I can't get R on the rail but even getting B on the rail is risky. How to get a bot to hold the ball?

@gmacpro . I have recently started this level and made some progress. But i think you are probably wrong about the ball crossing. i can not see any reason why it will not work

Took a while to see the gameplay and after guessing the final sections i struggled to work out how to get B up to a certain block-nice solution that was a bit unexpected.

@ridgerunner - I can get B from start to finish and when B goes over the falling ball B falls down too. After three misses, I used Mekostudio and still wasn't able to get B across after 4 or 5 more attempts. How did your B do?

@gmacpro . I have not been doing anything special. Got across first attempt. Tried a few more times and fell through once.

@ridgerunner - So another level that isn't stable on my device, I guess. I'll wait to hear from @Fendi Rahardian. It's really annoying spending all that time working forward and then backwards to find out others won but you can't.

Spoiler: Video Solution

@Fendi Rahardian .. solution.. my win was slightly shorter as i left R going up and down the stairs rather than step onto the draggable. Thus there was no need to do the first swap.

@ridgerunner Yup it can, in that part B must be in the draggable position (the one above has a wedge) first, after that R is swiped quickly with draggable to go up to the upper grass. Is it like that?

@Fendi Rahardian .yes like that.

@Fendi Rahardian - Sorry - your last move didn't work here. B wouldn't jump the opening.
