Before you start on any detailed design work you must create a moodboard. This is where you communicate your initial design ideas for your game. You should use it to get feedback from your game testers.
The moodboard should include inspirational materials/images for:
- the game genre and style
- settings/environments
- the characters
- any music, sound effects or speech
- anything else you think is important
You should annotate your moodboard to explain your ideas.
