Hi. I want to give my opinion, it feels so unfair, just take off your helmet and get an instant kill maybe could be a conterclock whit 5 or 10 secons before dead. In tutorial we learned to save oxygen. But sometimes you forgot to put back your helmet, and it would feel more realistic to have some time to save your ass jeje, And an autosave be cool too. But anyway Great game so far, keeping going, bye
