Old review: Better as offline play! 3/14/22: levels' time has been halved and making it impossible to play a level even with power ups. 3/21/22: they reduced the no ad price to a more reasonable range. However, I can no longer progress without paying for packages thanks to reduced times. 2:03 to sort over 120 (most likely even more) pairs? Been stuck on same level for a week,, no longer fun...Fix these problems = 5 stars
