It was in the new post maybe over a year ago.
It was a puzzler, the object was to push/pull a ball through the levels by changing the polarity of magnets.
I don't remember if it was the ball itself that changed its polarity or stationary magnets around the level.
The graphics were simple, and u saw the polarity of the magnets with colors changing between red and blue.
Anyone?
