This is a complete but brief walkthrough for the entire game. This means I will tell you what you have to do, but not WHY. I strongly suggest you play the game for yourself and only consult this walkthrough if you are really stuck.

• Whenever a new item is first acquired, its name is underlined
  
  
• All minigames' solutions are given in text format only
  
  
• Achievements are not mentioned, see other community guides for help with those
  
  
• "Talk to ..." usually means go through ALL available options
  
  
• "Switch to ..." (in Chapter 5) means either you have to do it manually or it happens automatically
  
  
• Chapter 5 is very long; I had to split it in two sections because of Steam's space restrictions per section
