Story level 3

Sightly more interesting. Good thing I'd played Portal before so I had my companion cube with me...

This one can be won without B.

If you quickly raise the lift that has the free draggable (FD) block, the FD will launch into the air. You can catch it in the air and move it over to drop it on the win block.

@MekaSage Yeah, using free dragables is always fraught with potential abuses. Found that out in one of my early maps when I'd created a slider without a rail to run on. Never heard of it before people told me. That's why this forum is a good learning environment.

@MekaSage What?WTF.It level ,these is bug???Original you passing,but these two passing my original.

@WorldStory - I don't think it's considered a bug. Free draggables are challenging to use. Here's the walkthrough of my solution:

I wasn't able to do what @MekaSage did using the free draggable so I think I had the right gameplay using all the elements. I like the launch though.

Need some challenge Buddy

I like the logic of the intended solution. A way to avoid the problem with the free draggable would be to design the level using a PillarR or PillarL bot instead. Since B can stand on them you can use similar logic puzzles to the ones in this level.
