Simply Higher or Lower

Hello! Maybe it's first review, but anyway: I played your game and to be honest i got bored in 5 minutes of playing. As for me, it would be good if you made some roguelike features in this game, for example: you guess card - you get points - you spent them on upgrades. And maybe then add "reset progress" button in settings. I'm not gonna post negative review because your game has really cool potential!
