Somehow, 17 years later, I'm drawn back to this game. A mixture of anxiety and calmness. A little bit of luck and planning, and the game isn't too terribly difficult. Excellent ambient soundtrack and just a good way to spend a few hours forgetting about the world around you.

Purchased for 2,45 euros. You can make this game either extremely relaxing or extremely challenging. On the one end you turn off the in-game music (fitting but very limited) and provide your own tracklist, and let the smallest movements guide you towards veeery slowly becoming the biggest.

About the game

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.
