I enjoy playing Hearts but could not continue with this version, unfortunately. There is quite a lot of room for improvement in the visual aspects of the game. I’ve played some other Hearts games where the use of color, player emoji, and spacing goes a long way to offer a more pleasurable player experience. For Seniors, these things also help to minimize confusion. For example, simply coloring each card suit differently will avoid accidentally selecting the wrong card. Like green for clubs, blue for diamonds, black for spades and red for hearts would distinguish the card suits from one another. Also, the use of sound could greatly enhance the user experience. These are just a few examples for GUI improvements I hope you might consider. I’ll check back down the road to see if the game is updated with Improved interface.
