Happy Lines is a strange game to say the least. One of the biggest problems is it's just trying so very hard to be happy. The aim is simple - match up rows or boxes of small squishy faces and they disappear. However, each time you move several new squishies invade. All looking so very, very happy. Perhaps it was me, and I can see this being a fun, challenging game for the right person, but I found it all rather irritating. That said, there are forty levels, the graphics are nice and colourful and you can switch to an arcade version.
