I lost interest too quickly
I did about 9 levels and then stopped because it was way too easy and each level basically looked the same. There were blocks that could only be deleted by matching over them twice, but that's not really hard. Maybe if I had continued to play I would have found later levels more of a challenge, but it just didn't hold my interest to get me that far. It just needs something to set it apart from other similar games that already have their own perks, power ups, etc.
