It's a fun game, and I completed several rounds of it.
During the game, the first problem I encountered was that the Setting card needed to be returned to its original position in order to take effect. I didn't understand this principle until today, and I wanted to play a simple breezy, but I was dragging the Setting card -> selecting breezy -> dragging the Start card, so I actually completed several rounds of balanced.
Additionally, rapidly dragging the entire deck of cards around can mess up the deck, possibly clicking on a card in the middle of the deck during the process of restoring the deck,
