Design Challenge

Hi all. If you tap the left gray cylinder, B comes out of the left door. While if you tap the right cylinder then B comes out of the right door. Challenge: design a level where you only change stuff behind the doors such that if you tap the left cylinder B will exit from the RIGHT door and if you tap the right cylinder B will exit from the LEFT door!

@Aleric - Like this?

@meko - Oh? Maybe i misunderstood - to me, "behind the doors" means "on the other side of the doors" (from B's perspective).

A bit ambiguous, but I think what's proposed is that we change things on B's side of the two doors.
Any limitations? Does the cylinders always need to be tappable? Can the player setup things before tapping?

@trids No, you're not alowed to change whats on this side of the exits.

@richardfu_ Yes, always tappable, and no set ups.

@richardfu_ , @meko - Topologically, it's all the same of course

@Aleric challenge accepted!

Ha ha, I knew you would richard . I wonder if you can make it smaller than me: I needed Max World cubed!!! Can't even put a box around it to hide how it works, or else I'd post here .

@Aleric Does the bot need to come out alive(not electrified)?

@richardfu_ Lol, yup, sorry.

I have it here:

I have to admit this is a painful one to make... and I did end up filling the entire space as well

Ha ha! Awesome! And it's a different solution from what I did!!
Let me remove my shielding box again and post it here...

@richardfu_ awesome, are you wizard? xD
