New Blocks Ladders and Lifts

How about ladders that bots can climb? These would be similar in shape to the fence pieces but flush to one side.

Also how about a block that rises up and down without the need for a slider. This would be called the "Lift" block. It would only move once you step on it.

Perhaps the lift starts at the top and you have to find a way to activate it so it goes down to the ground.

 

It would take up a lot less space. Compare the ladder to the steps needed to reach the same height:

 

I made a quick demo of a lift.

 

Yes, that's the idea! But I had to use existing blocks to show my concept.

 

I made my Lift Demo into a whole game!
