I feel like this is just an Literature lesson now.

A. Command line:

The command line is used to create a text/sentence of what you want Bernard to do.

E.g. "Walk to Mona Queena"

B. Verbs:

The Verbs are used to create the first part of the command line, after clicking one you can click a hotspot or object on the visual screen to finish the command line.

E.g. "Pick up Mona Queena"

C. Inventory

Basically what's in your pocket, you can use them to help with puzzles or give them to other characters.

E.g. "Use Pizza El Potassio on Mona Queena"

Puzzle policy:

There aren't any protagonist deaths in adventure games becuase players often experiment with their surroundings and what they have in their inventory. If there were to be death in adventure games, they should only be in battles (which makes more sense).

If you come across a death just by experimenting, you're bound to get annoyed and slightly anxious of what you might die of next so it's best to keep deaths in battles to be on the safe side.
