After a short testing beta Osmos from Hemisphere Games has finally arrived to GNU/Linux !
Osmos only costs $10 so you cannot afford not to buy it !
If you still aren’t sure, try the demo which is available as .deb, 32-bit .rpm, 64-bit .rpm, or .tar.gz formats !
As a compensation for those who bought the Windows version, they will also get the GNU/Linux version for free !
When I beta tested the game, it was nearly perfect (apart from a minor to fix sound issue and one little glitch that didn’t effect gameplay).
