Mazredugin

This game has one big innovation, where it has a personality test at the beginning and you end up playing one of four characters. Each of the 4 characters has a special section of the game that only they play. Then you work together with one friend, and then with all 4 to solve the game.

The plot is jumbled, and the writing is spare and choppy. The game is under implemented, and very short. However, the key concept makes it interesting.
