Development

I have decided to develop my second idea, about Fred in a coma, collecting memories and solving a mystery because this idea felt more creative, unique and interesting to myself.

I have spent this past week developing this game design idea, focusing on the story and the basics of the game. This is what I have come up with so far:
Prelude to Fred:
Game starts with a dark rainy scene, shows a blocked out figure finding something (e.g. a necklace) a shot of the characters eyes (or face with just eyes visible) shows a look of shock and then realisation come over his/her face as another blacked out figure appears over Freds shoulder, arms raised and hits Fred over the head.
Start of game: Shows Fred laying in a hospital bed, still silhouetted, but recognizable. Fred begins to get up and as you take control of the character, Fred realises he is in a bright white, sun lit, hospital ward and soft music is playing. Things seem to be all fine, untill you hear a voice around you, it is one of a nurse, relaying what has happened to you, but you cannot see her and soon find out she is talking to someone else. This is when it is made clear that Fred is not in the real world, but in a coma.

Basic story: Fred is in a coma and has to work out who he/she is. Fred remembers he/she was knocked out because of what he/she saw and must retrace memories of the the night and work out what happened, what she found, and who knocked her out.

Ideas for Crime Witnessed:
Muder/Attempted Murder - may be too dark
Illeagle Dealing - Drugs/Stolen Goods/ Bent Coppers
Con Artists - Unsolving a case, Twist could be Fred part of the Con gang.
Fraud
Arson - Would be good, Fred would be the only clue/evidence left if everything was burnt down
Theft - Jewel Thief, best for non physical violence or chance of death (like murder and arson)

Idea for game play:
The memories you collect in each level can lead to multiple memories, but not all will lead to the main story. This way the story will also be like a maze. Dead ends in the story will be of memories that are of little or no use to the main story e.g. a memory that proves someone was not at the crime scene.
