There's a achievement about all red buddies in deck and it works a bit tricky. There're some buddies which are partly red or pink-red(For examle Peeping or Harlequin Baby). And when i pick them in my deck and complete level achievement doesn't count. I tried some decks run and don't understand which buddy is red and which buddy is partly red or closer to pink. Im sure that I'm not alone with this small problem. How about highlight or mark these red buddies or add some buddies in "red" pool?
Anyway your game is amazing! And you are very cool :)
