  • 1 of 3: Don't worry; you have quite a bit of time left to solve this puzzle.
  • 2 of 3: If you are worried about the time, use the old "save-the-game-frequently" approach.  First, create a saved game as soon as you can.  Then explore around Stage 3.  As you solve a puzzle, or learn more about what to do, go back to your saved game, and then go straight to the puzzle solution, or whatever stage you discovered.  Then create a new saved game.  This will maximize your time, since all "exploring" time can now be skipped.
  • 3 of 3: Just continue on the rest of this Stage, without worrying about the oxygen remaining.
