Osmos HD

A lovely little ambient puzzle thing, in which you play a cell thing and make it your business to absorb others. The residue you fire out makes you smaller, though, so efficient use of your biological systems is a must. It's a chillout experience more than a game, with the surreal concept joined by some equally relaxing ambient music. A charmer.
