Catacombs

.

Provisional rating. Quite a lengthy win but I didn’t use the bot in the tower or two of the balls. No dodgy moves in my win though i had some difficulty dislodging one of the balls.

Thanks. My way uses the red in the tower and all the balls, so there must be some possibilities I didn't see.

Okay - I revisited the level and did win. I did use R in the tower and all the balls but I also used one trick in order to release B.

Spoiler: Trick

I used a ToA and/or a BB. Are one of these required to get B away from the tower?

@gmacpro No tricks needed. There's something at the top of the tower you can use to get B down.

I seen the rotor and figured it was just a red herring but obviously not. I did drop B but B went into hover mode so needed a restart. It's easier to do a BB or ToA to get B out. BTW, one of the balls fell (in the wrong place) when the metal roof was lifted so that also caused restarts. Overall a good level thanks.

Very enjoyable puzzle. Pushing the dark ball is a bit difficult.

Having come back and found the full gameplay, i think the level merits 5*. I am not sure i have found the right method of pushing the dark ball though.

Spoiler: My win

simple patience. Open the gate to let zbot out and while organising B , zbot will walk past the other zbot and eventually induce him to fall. One zbot will then climb the stairs to enable the dark ball to be pushed. In the presumed full gameplay it is R who is used to push the ball. But i have not found a good method with either nor with both bots combined

@ridgerunner I don't know how to do a 'spoiler' box, so I'll try not to say too much. But I think there may be another ball you haven't spotted.
And thanks very much for the 5 *.

I too changed my rating. Here's the way I did it without tricks. @ridgerunner - My way wasn't long only 3 minutes.

Spoiler: My Solution

Excellent clean logic level...Really I had a lot of fun with this one...Thanks for sharing @Jom

Btw... I did it like @gmacpro (with little differences) ...uuhhmm,I am almost sure that is tha intended way

@gmacpro Yes, that's what I had in mind. Thanks for your comments. It's really encouraging to get helpful and positive feedback.

@delator77 Thank you, I'm really glad you like it
