I say this because I honestly want this game to be better as it's the only Elevens solitaire game on the store. The numbers identifying each card ("2" "Q" "J") are tiny and in the center of the card. You can't play quickly, you have to READ every card. Just make them BIGGER.
In addition to this, the suits are the same size but are multi colored, so they grab the eye instead of the label. That's so useless and distracting considering suit is not important to Elevens. Just make the number big, bold, and larger than the suit.
