In Code C.O.L.O.N.B., the doubt is everywhere. The story isn't clear and not revealed. It's to you to interpet dialogs and events, to search clues and to make theories to understand the plot. Who are you ? Where are you ?
What is your goal ? What happened ? What happen ? And why ? Who are this character who're speaking ? Of what are they speaking ? Why are they speaking ? Why should you make theory about a game only available in french ?  (no, forget the last...).

Welcome in Code C.O.L.O.N.B., where Nothing is sure, where everything is theory. And where haste is your best
motivation...and your worst ennemy.

And yes, this game was made in less than two weeks, by only one person.
