Hemisphere Games “ambient” physics-based puzzler, Osmos, was released on the Mac last week and I finally got a chance to play this beautiful and very engaging indie game.  I wasn’t really sure at first if I was going to be satisfied by its gameplay, but after progressing through its relatively easy intro levels I was suddenly challenged with some very thought-provoking situations to navigate.  For $10 this one’s a no-brainer.  It really is as good as reviewers say it is.  Get the demo and try it out.
