Games that combine engaging gameplay with relaxation are few and far between but Osmos manages to balance the two quite well.
Osmos is a physics-based game which feature psychedelic graphics and a mellow ambient soundtrack to produce one of the more unusual arcade games on Mac. Quite simply, your aim is to increase the size of your "mote" by absorbing other motes. You propel yourself through space by thrusting dead matter behind you along the way trying to avoid destruction by attractors, repulsors and other motes hell bent on eating everything in their path. with similar abilities and goals as you.
Osmos will appeal to you depending on what you want from a game. As you progress through the levels and grow your more, both the gameplay and music have a surprisingly relaxing effect on the player. However, it will be a bit too chilled out and dull for those seeking something more action packed and interesting. The graphics are very limited and the gameplay does get repetitive after a while.
For those that want something a bit more relaxing than the average game though, Osmos will surely appeal.
