Okay, fun and cool but a few big problems, one is that it needs an alt-enter full screen command so a player can quickly fill out their screen and have a clear view of everything.
Second is that while the player may take care to place stickers so as to not place over numbers, the ai does NOT care and at times I have had a sticker over the upper left number leaving me blind to the value of the card, especially if I cannot go into fullscreen to get a good view of that bottom right number besides.
Really cool idea though besides and I would love to play more!
