The 1 star is based off my experience n is not reflective of the actual gameplay. I just downloaded this game yesterday n I got through my first puzzle fine but every game since then has crashed before I'm even halfway through it n I have to reopen the app. I've tried about 20 times but I can't get through a whole game n it sucks cause I feel this game has potential but it's unplayable for me n idk if it has to do with a problem playing on Android, a general problem, or if it's just a rare case.
