My biggest grip is still how long it takes to open a case (3-5hrs) but I have encountered a new problem. The use of swip tiles is a good concept however it's employed at the wrong times. They seem to love throwing you swipes when you are already hitting lots of tiles which can mess you up badly and also they have ones smaller than normal which can be infuriating as "Great" now acts as "Bad" so if you can't properly hit the small ones you can mess up as it takes 3 greats to destroy a streak
