I was checking on Play Store if 3.68 is finally available and I saw that the game screenshot still present the old graphics (probably back from 2014, I dunno, I didn't know the game at that time).
Since v3.70 holds the promise of a new set of both visual and sound effects, and since the game now features way more than 550 cards, I think it would be wise to update that info page and change the game screenshots. Also, it would be good to give the other stores a refresh.
