Matching puzzle games have been around for a very long time. From Bejeweled to Puzzle Quest 2, it seems like every permutation has been created, remixed, and re-released several times over. That's not necessarily a bad thing, of course, and Buddy Blitz banks on that fact with some lovely artwork and a streamlined matching game complete with cute animal friends!
There was a time, right around the middle of 2010, where you couldn't even sneeze without a new survival game falling out. Since then the survival genre has slowed to something of a more reasonable pace, with a lot of six month late "me too" releases broken up by the occasional hidden gem. Mechanic Panic definitely falls into the latter.
