It's a lovely game and I used to love it, but as many pointed out, it can just randomly wipe your progress, which happened to me. I reinstalled this after a long time and it is unfortunately unplayable for me at this point. Not only is the progress wiped on every launch, I can't connect it to Play services, and strangely, the taps register about half a centimeter above where I tap, and as you would imagine, I cannot tap where there isn't any screen, only thin air.
