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.

Some of the levels in the game are pretty fun while a few are plain frustrating.

Osmos has a unique gameplay mechanic that is executed well and its presentation is superb but ultimately the game is just too short.
