The audio is okay; I don't have any qualms with it, but nothing really jumps out at me (the music is geared for the kids). It's not necessarily my cup of tea, but it isn't necessarily bad (I have different tastes in music). KEM plays like many other drop puzzlers in the general sense; you match three blocks and they disappear. You can create chains and drop big piles of junk on your opponent. To destroy said junk and get your breathing room back, you must match blocks that are touching the junk. When you do so, the blocks and junk next to it will both vanish. KEM does have a trick up its sle
