The first two achievements are unmissable:
- The adventure has begun
- Warming up on fresh air

Hold spacebar to fast forward.

This game allows you to save directly on choice screens.

After you die or escape, the game returns you to the Stealth / Strength choice.

I've included some notes on what triggers certain choices/scenes.
