1. Avoid spoilers before playing
Now I’d better write this without spoilers, as you can’t have the tension without the surprises.
2. Listen to your surroundings and the music
A mixture of musical cues and positional audio should help you find the next clue - if you hear something go bump in the night, it’s up to you to investigate. If you hear a chime, pay attention because that object means something.
3. Read everything
Everything in the game holds some information about Greenwater and the events surrounding your current confinement. Some elements are obvious, such as newspaper articles, but others are a little more cryptic, this could include symbolism and gothic and classical references.
4. Re-cap
As you progress, you start to build up a collection of clues from the different locations you visit - these become available at the end of each chapter. This is a good time to take a step back and piece together who you might be and why you’re in the institution in the first place.
5. Don’t rush
All of the clues are there from the start. Take time to digest what is around you - it may become more apparent towards the end, but you can always start to analyse the clues earlier to form your own assumptions of why you’ve been locked away.
