Each answer in this 6x6 puzzle is only five letters long, because every row and column contains an "empty" square. (Since squares cannot be left empty, please use the rebus to mark them "XX").
Loving these. 7A reminded me of the quote “The opposite of play is not work, it’s depression.” Brian Sutton-Smith (most likely original source I could find). Fortunately DEPRESSION doesn’t fit unless you publish a 0-1-2-3 puzzle. That would send us mere mortals running into the hills.
