OMG this is so fun! played it for like hours again and again. If I'm allowed to note, I did get so many cards it went off the screen on both sides. This isn't really an issue as it just adds a little bit to the difficulty, but because the ability cards are added to the right side, I often was not even given the chance to use the ability card as it was just added off screen. I would recommend that cards be added to the middle of your deck and that metabolism cards be used right away. This game is truly amazing and doesn't need any changes if you don't want to make them. Just wanted to give some feedback!
