I wasn't really sure with this one. I couldn't tell whether people would be able to interpret the title easily enough. Perhaps it should change to easy?
Should this really be kids? The intended solution is easy to miss. I moved one of the single blocks first myself and solved it in 13 moves, but it wasn't that easy. Even when you're on the right path it's not totally obvious. It's trickier than Mysterious Orb (BLockoban) IMO. Should be Easy at least.
That said, regardless of which way you solve it, it's a solid puzzle. The intended solution is pretty elegant too. 5/5
