Enter the ambient world of Osmos: elegant, physics-based gameplay, dreamlike visuals, and a minimalist, electronic soundtrack. Your objective is to grow by absorbing other motes. Propel yourself by ejecting matter behind you. But be wise: ejecting matter also shrinks you. Relax… good things come to those who wait. Progress from serenely ambient levels into varied and challenging worlds. Confront attractors, repulsors and intelligent motes with similar abilities and goals as you.
Quite an interesting game concept - it's based on physics (and to some extent microbiology); you are a mote (a cell, if you like it) and you can absorb smaller motes through a process that resembles osmosis (just touch another smaller mote and you start absorbing it). The reverse also applies; touch a bigger mote and it absorbs you.
Propulsion is accomplished by clicking and releasing mass. Considering that this is a physics based game, you move with a momentum proportional to the mass you released.
Every level has a goal such as "become the biggest" or "become huge" or "absorb <x>" where <x> is a unique kind of mote such as an Ovarium or a Ferax.
Definitely relaxing in some stages thanks to the ambient music and the not-so-taxing (at least in most levels) gameplay.
Quite an enjoyable game!
