I've been playing this for 8 months and it just gets boring because they never add new games and the games become increasingly harder and harder to where my scores keep getting lower and lower. If it worked like it's supposed to, I'd be able to keep pace with the increased difficulty. I've read other reviews here and have taken to heart what people are saying about Luminosity continuing to bill after cancellation, so I went into my PayPal and removed Luminosity from my allowed recurring payments as well as cancelling my subscription on Luminosity. I paid for a year, so we'll see what happens in April, but it'll be PayPal's issue if they pay Luminosity and I do trust PayPal.
