It was ok at first.There's an ad after literally everything,can't do anything without watching some dumb 30s commercial.Whenever the background color changes it gives a lag spike which I find annoying, oh and the touch sensitivity is poor as well.Not to mention sometimes after trying to watch a add so I can continue playing the app close and doesn't even keep the mark I left off on.It glitches so bad and takes up so much space it's unbearable,wish there was a 0% button for such a cotasterfy🤦‍♀️
