On Discord, we were discussing The Longest Minute. At one point, GigaLem stated "At least there'll never be The Longest Second, because that's impossible."
So just to prove this wrong, I created a level with a 1 second time limit that's possible but not completely trivial. Don't get me wrong - it's extremely easy for an experienced player. And it's not meant to be treated as a serious level, just a "yes, this can be done" demonstration.
