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.
Decent experience, it really absorbed me for few hours, but then got bored. The game can be really challenging on higher levels and provides at least 5-10 hours of unique gameplay, all spiced up with mysterious music.
