Elephant Maze

This level has some good strong points: the concept of two levels where R steps over B, the design of the gate in the middle, the maze. But the area below the gate is not consistently accessible, R does not push the ball just to the right of the gate in the image, and there is a shortcut.

Spoiler: shortcut

The slider close to the win can be walked on using auto-pilot, and then it can be used to go up the wall by sliding it quickly. This skips the entire level.

I liked the level however I'm not a fan of levels where B needs to immediately move in order for a win. R didn't always knock the ball and I could never get a ball stay just below the center platform. I did win via this Shortcut.

Spoiler: Shortcut

Like @Block builder - I used the slider along with the other R to get up on the slider and then got up on the top level for the win. Maybe the slider is the only win?

@Block builder @gmacpro Thank you for playing!

Yes, R didn't always push the ball. And B also sometimes did not push the ball below the gate. I didn't know why this is happen. I played this level many times and sometimes B or R did not push the ball.

I didn't design this level with any shortcut. I don't realize that shortcut is exist. Now I know there is shortcut. Thank you.

Followed it through to the end using the planned win. Enjoyed it. Good design. Well thought out.

Nice logic level, thanks!
By the way, I didn't use some balls... don't know if there is a designed solution that requires all of them.

@chemi Thanks!

Spoiler: Balls

Two balls didn't use. Only for visual designed. In left image and right image (on grass).

Very nice logic/cooperation level...BTW...

Spoiler

I only use one R to complete the level

well I did it using the two R- bots,but one R is enough
