Demetrios: The BIG Cynical Adventure is a humorous point-and-click adventure game. It borrows from 90's classic adventures like Broken Sword or Runaway, but is played from a first-person perspective. During conversations character portraits are used. The game follows the antique dealer Bjorn Thonen who lives in Paris. After coming home drunk, he is robbed one night. The player has to help him investigate, with the help of his neighbour Sandra.
With bright, colorful art inspired by comic books, and played in a light mood, Demetrios include story sequences, puzzle-solving, mini-games, different Game Over sequences and collecting items such as cookies. There are also achievements and extras to unlock.
