I think this puzzle deserves a higher rating. It's very easy, but it is still really well executed. If I throw together a collection of clean professional maps with scaling difficulty in mind, this one definitely makes it in.

nice map, but way to easy.
good for beginners

I originally built this puzzle in hammer. Instead of the platform with the cube, there was a anti-gravity field that held the cube on a button on the ceiling and actually allowed you to walk around on the ceiling. I'm in the process of getting that level ported to the workshop.
