Glossary
  room      - a single game world's screen. referenced by 16-bit number 0xAALL, where AA - area# and LL - location#
  area      - geographic area - Mo, Chamaar, etc
  location  - coordinates of particular room in an area. usually in form of 0xXY, where X - map row, Y - map column
  character - an unique character (human or dino.) Has their own voice/dialog lines
  person    - instance of a character. Usually tied to specific room, but some may travel with you
  party     - a group of characters that travel with you
  object    - inventory item
  icon      - clickable rectangle with some action tied to it
  dialog    - a set of of dialog lines for character. further divided by categories and each entry may have associated
              condition to be validated
  global    - game-wide storage area. must be preserved when saving/loading
  phase     - current story progress. Incremented by 1 for minor events, by 0x10 for major advancements
