Beautiful, challenging and compelling game
This is one of the best games I have played. Great art, compelling story and challenging gameplay. Most importantly, it retains one's interest without the use of violence (short of your astronaut jumping off a cliff) as with so many games today. The only negative comment I have is the saved games are by default hidden by the OS. They are also placed in the cache folder which TimeMachine does not backup. Hopefully that will be corrected at some point.
