2. CONTEXT
Blind Trust is a school project
which was developped during our
first year of Master's Degree.
The Enjmin is the only public video
game school in France, and after
two years, students obtain a
Master's Degree in games and
interactive digital media.
The objectives our school set was to create an
interactive product which can be experienced by
anybody. A person who has never seen a video
game or a television, should be able to understand
all the interactions and their meanings.
Therefore, we drawed special attentions on the
tutorial and the different feedbacks, keeping in mind
an original gameplay.
During the end-of-the-year presentation, several
teachers and professionals encouraged us to
developp the game using XNA ; which is why we
saw an opportunity to share this game to everyone !

GAME MECHANICS
Blind Trust is a game about trust and distrust between two players.
The first player controls the only character on the screen and can't look at it, he has only sound feedbacks.
The second player sees what is on screen and has to guide the other player.
With the same character, each of the players has to collect their own specific items and avoid the enemies.
In a word, the players must cooperate to progress but they remain in a competition of victory.
During this whole document, we will name the player who controls the character without seeing it "the blind-
player" ; and the player who guides the other one "the sighted-player".
