If possible, could the buttons for the balancing on mobile be made slightly bigger? I don't know if this is only a problem for me but I often miss the button.
Also, checking the days and tips for the locked hearts is a little difficult on mobile since you have to hold down on the person and the heart to see the tip and it closes the whole drop down menu when you release either finger.
Otherwise, I love the game. I need more Casey in my life.
