Been loving the game since before the Steam update and decided to play it again now that it’s been updated, and…
I took a peek at the Steam screenshots and was curious. Apparently, if you only have one move left, it defaults to giving you the ace of clubs, which is actually an invalid move…
On a similar note, you’ve probably been told that the undo button doesn’t work if you have a card in your hand, and it feels reasonable that right clicking would mean “actually, put this card back where I took it and don’t make this move,” as long as you have undo enabled.
